When a UniProtKB keyword describes a concept that is within the scope of the Gene Ontology, it is investigated to determine whether it is appropriate to map the keyword to an equivalent term in GO. The mapping between UniProtKB keywords and GO terms is carried out manually. Definitions and hierarchies of the terms in the two resources are compared and the mapping generated will reflect the most correct correspondence. The translation table between GO terms and UniProtKB keywords is maintained by the UniProt-GOA team and available at http://www.geneontology.org/external2go/uniprotkb_kw2go. - -## Comments - -Formerly GOA:spkw. - - - -## OBSOLETE Gene Ontology annotation by the MGI curatorial staff, Mouse Locus Catalog - - * id: [GO_REF:0000006](https://github.com/geneontology/go-site/blob/master/metadata/gorefs/goref-0000006.md) - * year: 2001 - * citation: [PMID:11374909](http://www.ncbi.nlm.nih.gov/pubmed/11374909) - * authors: Mouse Genome Informatics scientific curators - * ext xref: MGI:2152097 - * ext xref: J:72246 - - - -For annotations documented via this citation, curators used the information in the Mouse Locus Catalog in MGI to assign GO terms.

When using HMMs with proteins, the HMM is a statistical model of the patterns of the amino acids found in a multiple alignment of a set of proteins called the "seed". Seed proteins are chosen based on sequence similarity to each other. Seed members can be chosen with different levels of relationship to each other. They can be members of a superfamily (ex. ABC transporter, ATP-binding proteins), they can all share the same exact specific function (ex. biotin synthase) or they could share another type of relationship of intermediate specificity (ex. subfamily, domain). New proteins can be scored against the model generated from the seed according to how closely the patterns of amino acids in the new proteins match those in the seed. There are two scores assigned to the HMM which allow annotators to judge how well any new protein scores to the model. Proteins scoring above the "trusted cutoff" score can be assumed to be part of the group defined by the seed. Proteins scoring below the "noise cutoff" score can be assumed to NOT be a part of the group. Proteins scoring between the trusted and noise cutoffs may be part of the group but may not. One of the important features of HMMs is that they are built from a multiple alignment of protein sequences, not a pairwise alignment. This is significant, since shared similarity between many proteins is much more likely to indicate shared functional relationship than sequence similarity between just two proteins. The usefulness of an HMM is directly related to the amount of care that is taken in chosing the seed members, building a good multiple alignment of the seed members, assessing the level of specificity of the model, and choosing the cutoff scores correctly. In order to properly assess what functional relevance an above-trusted scoring HMM match has to a query, one must carefully determine what the functional scope of the HMM is. If the HMM models proteins that all share the same function then it is likely possible to assign a specific function to high-scoring match proteins based on the HMM. If the HMM models proteins that have a wide variety of functions, then it will not be possible to assign a specific function to the query based on the HMM match, however, depending on the nature of the HMM in question, it may be possible to assign a more general (family or subfamily level) function. In order to determine the functional scope of an HMM, one must carefully read the documentation associated with the HMM. The annotator must also consider whether the function attributed to the proteins in the HMM makes sense for the query based on what is known about the organism in which the query protein resides and in light of any other information that might be available about the query protein. After carefully considering all of these issues the annotator makes an annotation. - - - -## Pairwise alignment (TIGR) - - * id: [GO_REF:0000012](https://github.com/geneontology/go-site/blob/master/metadata/gorefs/goref-0000012.md) - * year: 2003 - * authors: Michelle Gwinn, TIGR curators - - - -Pairwise alignments are generated by taking two sequences and aligning them so that the maximum number of amino acids in each protein match, or are similar to, each other. Tools such as BLAST work by comparing a protein-of-interest individually with every protein in a database of known protein sequences and retaining only those matches with a high probability of being significant. Basic BLAST generates local alignments between proteins for regions of high similarity. Other pairwise alignment tools attempt to generate global (full-length) protein alignments. A tool called Blast_Extend_repraze (BER, http://ber.sourceforge.net) has some benefits over basic BLAST. Input into the BER tool includes the underlying DNA sequence for each protein as well as 300 nucleotides upstream and downstream of the predicted boundaries of the protein coding sequence. This allows annotators to see the DNA sequence that underlies the query protein as part of the alignment. In addition, the BER tool is able to look for continuation of regions of similarity through frameshifts and in-frame stop codons. If such regions are found the alignment is continued. BER searches are done in a two-step process: step one is a BLAST search against a non-redundant protein database, significant BLAST hits are stored in a mini-database for each query protein; step two is a modified Smith-Waterman alignment between the query and the proteins in its mini-database. In order to assess whether a given BER alignment is good enough to assert that the query shares the function of the match protein, one must look at a several factors. First of all, the match protein must itself be experimentally characterized in order to avoid transitive annotation errors. In addition, any residues or secondary structures known to be important for function in the match protein must be conserved in the query. The alignment should be visually inspected to look for any areas of lesser quality that might indicate the two proteins do not share the same function. Although it is impossible to set cutoff values for percent identity and length of match that will apply for every alignment, there are some guidelines. In general at least 40% identity that extends over the full lengths of both proteins is required in order to even consider functional equivalence. However, this percentage is highly dependent on the length and complexity of the proteins. 40% identity between two proteins 500 amino acids long is much more significant that 40% identity between two proteins that are only 100 amino acids long. Therefore, the annotator's experience and knowledge of what is considered significant for the organism and protein family in question is very important. Some sets of proteins are much more highly conserved than others and therefore tolerances for percent identity may have to be adjusted. Finally, the alignment must be considered in the context of what else is known about the query protein and the organism as a whole. - - - -## Use of the ND evidence code for Gene Ontology (GO) terms. - - * id: [GO_REF:0000015](https://github.com/geneontology/go-site/blob/master/metadata/gorefs/goref-0000015.md) - * year: 2002 - * authors: GO Curators - * ext xref: ECO:0000307 - * ext xref: AspGD_REF:ASPL0000111607 - * ext xref: CGD_REF:CAL0125086 - * ext xref: dictyBase_REF:2 - * ext xref: dictyBase_REF:9851 - * ext xref: FB:FBrf0159398 - * ext xref: MGI:MGI:2156816 - * ext xref: RGD:1598407 - * ext xref: SGD_REF:S000069584 - * ext xref: TAIR:Communication:1345790 - * ext xref: ZFIN:ZDB-PUB-031118-1 - * ext xref: GO_REF:nd - - -Direct annotations to any of the three root terms 'molecular function; GO:0003674', 'biological process; GO:0008150' or 'cellular component; GO:0005575' indicate that curators have found no data supporting an annotation to a more specific term, either in the literature and/or by sequence similarity for this gene or protein as of the date of the annotation. - - - -## OBSOLETE dictyBase 'Inferred from Electronic Annotation (BLAST method)' - - * id: [GO_REF:0000018](https://github.com/geneontology/go-site/blob/master/metadata/gorefs/goref-0000018.md) - * year: 2005 - * authors: DictyBase curators - * ext xref: dictyBase_REF:10158 - - - -Gene Ontology (GO) annotations with the evidence code 'Inferred from Electronic Annotation' (IEA) are assigned automatically to gene products in dictyBase.

Up until this point, the GO has had a very shallow representation of processes pertaining to the nervous system. In June 2006, curators from MGI and ZFIN met with researchers studying central nervous system development to improve the representation of these processes in GO. In particular, emphasis was placed on three areas that are being addressed actively in current research: forebrain development, hindbrain development and neural tube development. This collaboration resulted in the addition of over 500 terms that reflect the development of the forebrain, the hindbrain, and the neural tube from the perspective of biological process and anatomical structure. - - - -## Improving the representation of immunology in the biological process Ontology - - * id: [GO_REF:0000022](https://github.com/geneontology/go-site/blob/master/metadata/gorefs/goref-0000022.md) - * year: 2005 - * authors: Alison Deckhut Augustine (1), Alan Collmer (2), Judith A.

However, particularly in the biological process ontology, the initial set of terms relating to immunology failed to cover the breadth of known immunological processes, and in many cases diverged from current usage and understanding in their names, definitions, and ontological placement. As part of a larger effort to improve the representation of immunology in the GO, a GO Content Meeting was held November 15-16, 2005, at The Institute for Genomic Research, to discuss improvements to representation of immunology in the biological process ontology of the GO. As a result of the meeting, a number of high level terms for immunological processes were created, an overall structure for immunologically related terms was established, and certain existing terms were renamed or redefined as well to bring them in line with current usage. - - - -## Gene Ontology annotation based on UniProtKB Subcellular Location vocabulary mapping. - - * id: [GO_REF:0000023](https://github.com/geneontology/go-site/blob/master/metadata/gorefs/goref-0000023.md) - * year: 2007 - * authors: GOA curators, UniProt curators - * ext xref: SGD_REF:S000125578 - - - -Transitive assignment of GO terms based on the UniProtKB Subcellular Location vocabulary. UniProtKB Subcellular Location is a controlled vocabulary used to supply subcellular location information to UniProtKB entries in the SUBCELLULAR LOCATION lines.

Annotations are created when a curator judges that the sequence of a protein shows high similarity to another protein that has annotation(s) supported by experimental evidence (and therefore display one of the evidence codes EXP, IDA, IGI, IMP, IPI or IEP). Annotations resulting from the transfer of GO terms display the 'ISS' evidence code and include an accession for the protein from which the annotation was projected in the 'with' field (column 8). This field can contain either a UniProtKB accession or an IPI (International Protein Index) identifier. Only annotations with an experimental evidence code and which do not have the 'NOT' qualifier are transferred. Putative orthologs are chosen using information combined from a variety of complementary sources. Potential orthologs are initially identified using sequence similarity search programs such as BLAST. Orthology relationships are then verified manually using a combination of resources including sequence analysis tools, phylogenetic and comparative genomics databases such as Ensembl Compara, INPARANOID and OrthoMCL, as well as other specialised databases such as species-specific collections (e.g. HGNC's HCOP). In all cases curators check each alignment and use their experience to assess whether similarity is considered to be strong enough to infer that the two proteins have a common function so that they can confidently project an annotation. While there is no fixed cut-off point in percentage sequence similarity, generally proteins which have greater than 30% identity that covers greater than 80% of the length of both proteins are examined further. For mammalian proteins this cut-off tends to be higher, with an average of 80% identity over 90% of the length of both proteins. Strict orthologs are desirable but not essential. In general, when there is evidence of multiple paralogs for a single species, annotations using less specific GO terms are transferred to the paralogs, however, annotations using more specific GO terms may be transferred to the most similar paralog in each species, this decision is taken on a case by case basis and may be influenced by statements by researchers in the field.

Genes in an operon are all transcribed into one mRNA. Generally the genes in the operons code for proteins that all have related functions. For example, they may be the steps in a biochemical pathway, or they may be the subunits of a protein complex. Often the genes in operons shared between organisms are syntenic; that is, the same genes are in the same order in the operon in different species. When assessing sequence-comparison-based evidence during the process of manual annotation of a genome, it is often the case that some of the genes in the operon will have strong sequence-based evidence while others will have weak evidence. If seen alone, not in the presence of an operon, the weak evidence in question may not be sufficient to make a functional annotation. However, in the presence of an operon in which there is strong evidence for some of the genes, the very presence of the gene in the operon is a strong indication that the gene shares in the process carried out by the operon. If the putative function is one expected to exist for the process in question and particularly if that function has been observed in the same operon in another species, then the annotation should be made. This type of evidence is inferred from the context of the gene in an operon, and therefore the evidence code is IGC "inferred from genomic context." - - - -## OBSOLETE Improving the representation of muscle biology in the biological process and cellular component ontologies. - - * id: [GO_REF:0000026](https://github.com/geneontology/go-site/blob/master/metadata/gorefs/goref-0000026.md) - * year: 2007 - * citation: [PMID:19178689](http://www.ncbi.nlm.nih.gov/pubmed/19178689) - * authors: Jennifer Deegan nee Clark (1, 5), Alexander D.

The aims of this effort were to provide a comprehensive representation of muscle biology in the biological process and cellular component ontologies and to improve the organization of muscle-specific terms to better describe the current knowledge of biological mechanisms in muscle tissue. Thus, the collaboration brought together experts in several areas of muscle biology and physiology who carried out a thorough review of the existing GO muscle terms as these terms were largely created by non-muscle experts using older definitions. In particular, several areas are being addressed actively in current research: the biological processes of muscle contraction, muscle plasticity, muscle development, and muscle regeneration; and the sarcoplasmic reticulum and membrane delimited compartments. This work resulted in the addition of 159 new terms and in the modification of 57 terms to bring them in line with current usage.

Standard BLASTP from NCBI was used (http://www.ncbi.nih.gov/blast) to iteratively search reciprocal best hits and thus identify orthologs between predicted proteins of Magnaporthe grisea and GO proteins from multiple organisms with published association to GO terms. The alignments were manually reviewed for those hits with e-value equal to zero and with 80% or better coverage of both query and subject sequences, and for those hits with e<=10^-20, pid >=35 and sequence coverage >=80%. Furthermore, experimental or reviewed data from literature and other sources were incorporated into the GO annotation. IDA was assigned to an annotation if normal function of its gene was determined through transfections into a cell line and overexpression. IEP was assigned to an annotation if according to microarray experiments, its gene was upregulated in a biological process and the fold change was equal to or bigger than 10, or if according to Massively Parallel Signature Sequencing (MPSS), its gene was upregulated only in a certain biological process and the fold change was equal to or bigger than 10. ISS was assigned to an annotation if the entry at the With_column was experimentally characterized and the pairwise alignments were manually reviewed. IGC was assigned to an annotation if it based on comparison and analysis of gene location and structure, clustering of genes, and phylogenetic reconstruction of these genes. RCA was assigned to an annotation if it based on integrated computational analysis of whole genome microarray data, and matches to InterPro, pfam, and COG etc. IEA was assigned to an annotation if its function assignment based on computational work, and no manual review was done. - - - -## OBSOLETE Gene Ontology annotation based on information extracted from curated UniProtKB entries - - * id: [GO_REF:0000029](https://github.com/geneontology/go-site/blob/master/metadata/gorefs/goref-0000029.md) - * year: 2007 - * authors: GOA-UniProt curators - - - -Active 2001-2007. - -Method by which GO terms were manually assigned to UniProt KnowledgeBase accessions, using either a NAS or TAS evidence code, by applying information extracted from the corresponding publicly-available, manually curated UniProtKB entry.

A rule has two parts. The first is the set of conditions that must be met for the rule to fire. The second is the set actions to be taken for rules that have fired. BGRB rules are designed to serve as proxies for the annotators that create them. They have very high fidelity but may have low coverage. Types of evidence used in combination include HMM hits and BLAST matches, hits to neighboring genes, pathway reconstruction reports from the Genome Properties system, and species taxonomy. BLAST matches are described by a number of separate parameters for raw score, percent sequence identity, and coverage of total sequence length by the match region. These parameters are customized for each protein family in order to achieve high fidelity in automated annotation systems. The flexible syntax makes it possible to use existing protein family classifiers, such as Pfam and TIGRFAMs HMMs, in new ways. It is especially useful in assigning GO terms to proteins such as SelD (selenide, water dikinase) that have different roles in different contexts. - - - -## OBSOLETE NIAID Cell Ontology Workshop - - * id: [GO_REF:0000031](https://github.com/geneontology/go-site/blob/master/metadata/gorefs/goref-0000031.md) - * year: 2008 - * authors: Alexander D.

Supportive - Subcellular localization supported by literature.
1) One/multiple localizations supported by literature.
2) Multiple localizations partly supported (at least one) by literature.
3) One/multiple localizations in cytoplasm (i.e. Golgi, mitochondria, ER etc) with literature supporting cytoplasmic localization.

GO Cellular Component terms are manually assigned by curators studying fluorescence microscope images of cells labelled with GFP-fused cDNAs. Protein coding regions of novel full length cDNAs are tagged with the coding sequence of the green fluorescent protein, the fusion proteins are then expressed and analyzed for their subcellular localization.

For certain terms, however, there is obvious implicit taxon specificity, such that the term should only be used to categorize gene products from particular species. Taxon specificity of GO terms is captured using relationships such as "only_in_taxon" and "never_in_taxon". All taxon constraints are inherited by sub-types and parts of the GO term they are applied to. Taxon constraints are used to prevent inappropriate annotations from being made by curators as well as to identify pre-existing annotations that violate the taxon constraints. Errors in annotations are automatically detected by looking for inconsistencies between the taxonomic origin of the annotated gene products and the implicit taxon specificity of the GO terms. The inconsistencies are passed on to curators for correction, in some cases the constraints need to be tightened or relaxed or the structure of the ontology needs to be adjusted. The taxon constraints are further described in this publication: Deegan, Dimmer and Mungall.

In particular, this GO reference describes the criteria used to assign evidence codes ISS, ISA, ISO, ISM, IGC and ND. To assign ISS, ISA, ISO and ISM evidence codes, SEA-PHAGE biocurators use a varied array of bioinformatics tools to establish homology and conservation of sequence and structure functional determinants with proteins from multiple organisms with published association to experimental GO terms and lacking NOT qualifiers. These proteins are referenced in the WITH field of the annotation using their xref database accession. The primary tools for homology search in ISS, ISA, ISO and ISM assignments are BLASTP and HHpred, using a maximum e-value of 10^-7 for BLASTP and a minimum probability of 0.9 for HHpred, and manual inspection of alignments in both cases. For ISS and ISA assignments, BLASTP alignments are required to have at least 75% coverage and 30% identity. For ISO assignments, orthology is further validated using reciprocal BLASTP with the identified hit. For HHpred results, ISS or ISM annotations are made only if the source for the original GO annotation explicitly defines a matched domain function, or if more than half of the domains of the query protein are identified in the matching protein. All ISS, ISA, ISO and ISM assignments entail the manual verification of the source for the GO term in the matching protein sequence and critical curator assessment of the likelihood of preservation of function, process or component in the context of bacteriophage biology. IGC codes are assigned on the basis of suggestive evidence for function based on synteny, as inferred from whole-genome comparative analyses of multiple bacteriophage genomes using primarily the Phamerator software platform, and with special emphasis on the bacteriophage virion structure and assembly genes. When extensive review of published literature on putative homologs reveals no experimental evidence of function, component or process for a particular gene product, it is assigned an ND evidence code and annotated to the root term for Cellular Component, Molecular Function and Biological Process. As part of the review process for assignment of ISS, ISA, ISO, IGC and ISM evidence codes, SEA-PHAGE curators are required to analyze the reference literature for identified matches and shall perform GO annotations with appropriate evidence codes if these were not available. - - - -## Automated transfer of experimentally-verified GO annotation data to close orthologs - - * id: [GO_REF:0000101](https://github.com/geneontology/go-site/blob/master/metadata/gorefs/goref-0000101.md) - * year: 2015 - * authors: Sascha Steinbiss, GeneDB curators - - - -This reference is used to describe functional annotations transferred from one or more reference ("source") organisms to a newly annotated ("target") organism on the basis of ortholog cluster membership.

In particular, this GO reference describes the criteria used to make annotations based on evidence codes ISS, ISA, ISO, ISM and IGC. To perform ISS-, ISA-, and ISO-based annotations on a gene product, CACAO biocurators use sequence- and structure-based search algorithms (e.g. BLASTP, HHPred) to establish homology, conservation of sequence and structure functional determinants between the target gene product and gene products from other organisms with published GO annotations supported by experimental codes and lacking NOT qualifiers. These gene products are referenced in the WITH field of the annotation using their xref database accession. ISM-based annotations make use of published computational methods (e.g. TMHMM, SignalP) to predict gene product structure, localization or function. IGC-based annotations are made on the basis of suggestive evidence for function based on synteny. Parameters and criteria for use of all computational methods (e.g. e-value) are listed and versioned in the publicly available CACAO documentation (http://gowiki.tamu.edu/). Annotations made by CACAO biocurators are reviewed by CACAO team instructors before their release. - - - -## Gene Ontology annotation of human sequence-specific DNA binding transcription factors (DbTFs) based on the TFClass database - - * id: [GO_REF:0000113](https://github.com/geneontology/go-site/blob/master/metadata/gorefs/goref-0000113.md) - * year: 2018 - * authors: Marcio Luis Acencio (1), George Georghiou (2), Sandra Orchard (2), Liv Thommensen (1), Martin Kuiper (1) and Astrid Lægreid (1).

(1) European Bioinformatics Institute (EBI), Hinxton, Cambridgeshire, United Kingdom - - - -Method for transferring manual annotations to an entry based on a curator's judgment of its similarity to a putative homolog that has annotations that are supported with experimental evidence. Annotations are created when a curator judges that the sequence, composition and function of a complex shows high similarity to another complex that has annotation(s) supported by experimental evidence (and therefore display one of the evidence codes ECO:0000353 [IPI] or ECO:0005543). Annotations resulting from the transfer of GO terms display the ECO:0005610, ECO:0005544 or ECO:0005546 evidence codes and include an accession for the complex from which the annotation was projected in the 'with/from' field (column 8). This field MUST contain a Complex Portal accession identifier. Putative homologs are chosen using information combined from a variety of complementary sources. Potential homologs are initially identified using sequence similarity search programs such as BLAST. Homologous relationships are then verified manually using a combination of resources including sequence analysis tools, phylogenetic and comparative genomics databases such as Ensembl Compara, INPARANOID and OrthoMCL, as well as other specialised databases such as species-specific collections (e.g. HGNC's HCOP). In all cases curators check the alignments for each complex component and use their experience to assess whether similarity is considered to be strong enough to infer that the two proteins have a common function so that they can confidently project an annotation. While there is no fixed cut-off point in percentage sequence similarity, generally proteins which have greater than 70% identity that covers greater than 90% of the length of both proteins are examined further. Whilst we expect subunit composition to be conserved between closely related species, this is not an absolute rule and orthologous complexes may differ if a subunit cannot be traced in one species or is experimentally shown not to be present. When there is evidence of multiple paralogs for a single species, multiple variants of the complex can be inferred. - - - -## Automatic Gene Ontology annotation of non-coding RNA sequences through association of Rfam records with GO terms - - * id: [GO_REF:0000115](https://github.com/geneontology/go-site/blob/master/metadata/gorefs/goref-0000115.md) - * year: 2018 - * authors: RNAcentral (1).

When using HMMs with proteins, the HMM is a statistical model of the patterns of the amino acids found in a multiple alignment of a set of proteins called the "seed". Seed proteins are chosen based on sequence similarity to each other. Seed members can be chosen with different levels of relationship to each other. They can be members of a superfamily (ex. ABC transporter, ATP-binding proteins), they can all share the same exact specific function (ex. biotin synthase) or they could share another type of relationship of intermediate specificity (ex. subfamily, domain). New proteins can be scored against the model generated from the seed according to how closely the patterns of amino acids in the new proteins match those in the seed. There are two scores assigned to the HMM which allow annotators to judge how well any new protein scores to the model. Proteins scoring above the "trusted cutoff" score can be assumed to be part of the group defined by the seed. Proteins scoring below the "noise cutoff" score can be assumed to NOT be a part of the group. Proteins scoring between the trusted and noise cutoffs may be part of the group but may not. One of the important features of HMMs is that they are built from a multiple alignment of protein sequences, not a pairwise alignment. This is significant, since shared similarity between many proteins is much more likely to indicate shared functional relationship than sequence similarity between just two proteins. The usefulness of an HMM is directly related to the amount of care that is taken in chosing the seed members, building a good multiple alignment of the seed members, assessing the level of specificity of the model, and choosing the cutoff scores correctly. In order to properly assess what functional relevance an above-trusted scoring HMM match has to a query, one must carefully determine what the functional scope of the HMM is. If the HMM models proteins that all share the same function then it is likely possible to assign a specific function to high-scoring match proteins based on the HMM. If the HMM models proteins that have a wide variety of functions, then it will not be possible to assign a specific function to the query based on the HMM match, however, depending on the nature of the HMM in question, it may be possible to assign a more general (family or subfamily level) function. In order to determine the functional scope of an HMM, one must carefully read the documentation associated with the HMM. The annotator must also consider whether the function attributed to the proteins in the HMM makes sense for the query based on what is known about the organism in which the query protein resides and in light of any other information that might be available about the query protein. After carefully considering all of these issues the annotator makes an annotation. diff --git a/metadata/gorefs/goref-0000012.md b/metadata/gorefs/goref-0000012.md deleted file mode 100644 index 22f66af8..00000000 --- a/metadata/gorefs/goref-0000012.md +++ /dev/null @@ -1,11 +0,0 @@ ---- -authors: Michelle Gwinn, TIGR curators -id: "GO_REF:0000012" -is_obsolete: false -year: 2003 -layout: goref ---- - -## Pairwise alignment (TIGR) - -Pairwise alignments are generated by taking two sequences and aligning them so that the maximum number of amino acids in each protein match, or are similar to, each other. Tools such as BLAST work by comparing a protein-of-interest individually with every protein in a database of known protein sequences and retaining only those matches with a high probability of being significant. Basic BLAST generates local alignments between proteins for regions of high similarity. Other pairwise alignment tools attempt to generate global (full-length) protein alignments. A tool called Blast_Extend_repraze (BER, http://ber.sourceforge.net) has some benefits over basic BLAST. Input into the BER tool includes the underlying DNA sequence for each protein as well as 300 nucleotides upstream and downstream of the predicted boundaries of the protein coding sequence. This allows annotators to see the DNA sequence that underlies the query protein as part of the alignment. In addition, the BER tool is able to look for continuation of regions of similarity through frameshifts and in-frame stop codons. If such regions are found the alignment is continued. BER searches are done in a two-step process: step one is a BLAST search against a non-redundant protein database, significant BLAST hits are stored in a mini-database for each query protein; step two is a modified Smith-Waterman alignment between the query and the proteins in its mini-database. In order to assess whether a given BER alignment is good enough to assert that the query shares the function of the match protein, one must look at a several factors. First of all, the match protein must itself be experimentally characterized in order to avoid transitive annotation errors. In addition, any residues or secondary structures known to be important for function in the match protein must be conserved in the query. The alignment should be visually inspected to look for any areas of lesser quality that might indicate the two proteins do not share the same function. Although it is impossible to set cutoff values for percent identity and length of match that will apply for every alignment, there are some guidelines. In general at least 40% identity that extends over the full lengths of both proteins is required in order to even consider functional equivalence. However, this percentage is highly dependent on the length and complexity of the proteins. 40% identity between two proteins 500 amino acids long is much more significant that 40% identity between two proteins that are only 100 amino acids long.

Some sets of proteins are much more highly conserved than others and therefore tolerances for percent identity may have to be adjusted. Finally, the alignment must be considered in the context of what else is known about the query protein and the organism as a whole. diff --git a/metadata/gorefs/goref-0000015.md b/metadata/gorefs/goref-0000015.md deleted file mode 100644 index 4bbc5b47..00000000 --- a/metadata/gorefs/goref-0000015.md +++ /dev/null @@ -1,23 +0,0 @@ ---- -authors: GO Curators -external_accession: - - ECO:0000307 - - AspGD_REF:ASPL0000111607 - - CGD_REF:CAL0125086 - - dictyBase_REF:2 - - dictyBase_REF:9851 - - FB:FBrf0159398 - - MGI:MGI:2156816 - - RGD:1598407 - - SGD_REF:S000069584 - - TAIR:Communication:1345790 - - ZFIN:ZDB-PUB-031118-1 - - GO_REF:nd -id: "GO_REF:0000015" -is_obsolete: false -year: 2002 -layout: goref ---- - -## Use of the ND evidence code for Gene Ontology (GO) terms. -Direct annotations to any of the three root terms 'molecular function; GO:0003674', 'biological process; GO:0008150' or 'cellular component; GO:0005575' indicate that curators have found no data supporting an annotation to a more specific term, either in the literature and/or by sequence similarity for this gene or protein as of the date of the annotation. diff --git a/metadata/gorefs/goref-0000018.md b/metadata/gorefs/goref-0000018.md deleted file mode 100644 index bf2718e9..00000000 --- a/metadata/gorefs/goref-0000018.md +++ /dev/null @@ -1,13 +0,0 @@ ---- -authors: DictyBase curators -external_accession: - - dictyBase_REF:10158 -id: "GO_REF:0000018" -is_obsolete: True -year: 2005 -layout: goref ---- - -## OBSOLETE dictyBase 'Inferred from Electronic Annotation (BLAST method)' - -Gene Ontology (GO) annotations with the evidence code 'Inferred from Electronic Annotation' (IEA) are assigned automatically to gene products in dictyBase.

Annotations are created when a curator judges that the sequence of a protein shows high similarity to another protein that has annotation(s) supported by experimental evidence (and therefore display one of the evidence codes EXP, IDA, IGI, IMP, IPI or IEP). Annotations resulting from the transfer of GO terms display the 'ISS' evidence code and include an accession for the protein from which the annotation was projected in the 'with' field (column 8). This field can contain either a UniProtKB accession or an IPI (International Protein Index) identifier. Only annotations with an experimental evidence code and which do not have the 'NOT' qualifier are transferred. Putative orthologs are chosen using information combined from a variety of complementary sources. Potential orthologs are initially identified using sequence similarity search programs such as BLAST. Orthology relationships are then verified manually using a combination of resources including sequence analysis tools, phylogenetic and comparative genomics databases such as Ensembl Compara, INPARANOID and OrthoMCL, as well as other specialised databases such as species-specific collections (e.g. HGNC's HCOP). In all cases curators check each alignment and use their experience to assess whether similarity is considered to be strong enough to infer that the two proteins have a common function so that they can confidently project an annotation. While there is no fixed cut-off point in percentage sequence similarity, generally proteins which have greater than 30% identity that covers greater than 80% of the length of both proteins are examined further. For mammalian proteins this cut-off tends to be higher, with an average of 80% identity over 90% of the length of both proteins. Strict orthologs are desirable but not essential. In general, when there is evidence of multiple paralogs for a single species, annotations using less specific GO terms are transferred to the paralogs, however, annotations using more specific GO terms may be transferred to the most similar paralog in each species, this decision is taken on a case by case basis and may be influenced by statements by researchers in the field.

Genes in an operon are all transcribed into one mRNA. Generally the genes in the operons code for proteins that all have related functions. For example, they may be the steps in a biochemical pathway, or they may be the subunits of a protein complex. Often the genes in operons shared between organisms are syntenic; that is, the same genes are in the same order in the operon in different species. When assessing sequence-comparison-based evidence during the process of manual annotation of a genome, it is often the case that some of the genes in the operon will have strong sequence-based evidence while others will have weak evidence. If seen alone, not in the presence of an operon, the weak evidence in question may not be sufficient to make a functional annotation. However, in the presence of an operon in which there is strong evidence for some of the genes, the very presence of the gene in the operon is a strong indication that the gene shares in the process carried out by the operon. If the putative function is one expected to exist for the process in question and particularly if that function has been observed in the same operon in another species, then the annotation should be made.

The aims of this effort were to provide a comprehensive representation of muscle biology in the biological process and cellular component ontologies and to improve the organization of muscle-specific terms to better describe the current knowledge of biological mechanisms in muscle tissue. Thus, the collaboration brought together experts in several areas of muscle biology and physiology who carried out a thorough review of the existing GO muscle terms as these terms were largely created by non-muscle experts using older definitions. In particular, several areas are being addressed actively in current research: the biological processes of muscle contraction, muscle plasticity, muscle development, and muscle regeneration; and the sarcoplasmic reticulum and membrane delimited compartments. This work resulted in the addition of 159 new terms and in the modification of 57 terms to bring them in line with current usage.

A novel cloning technology was used to rapidly generate N- and C-terminal green fluorescent protein fusions of cDNAs to examine the intracellular localizations of expressed fusion proteins in living cells. GO Cellular Component terms are manually assigned by curators studying fluorescence microscope images of cells labelled with GFP-fused cDNAs. Protein coding regions of novel full length cDNAs are tagged with the coding sequence of the green fluorescent protein, the fusion proteins are then expressed and analyzed for their subcellular localization.
Prior to February 2013, all LIFEdb annotations were referenced by PMID: 11256614 (Simpson et al. 2000 EMBO Rep. 1:287-292), a paper describing the protein subcellular localization pilot study and methodology used by LIFEdb. However, it has been decided that these annotations are more correctly described by a GO reference.

For certain terms, however, there is obvious implicit taxon specificity, such that the term should only be used to categorize gene products from particular species. Taxon specificity of GO terms is captured using relationships such as "only_in_taxon" and "never_in_taxon". All taxon constraints are inherited by sub-types and parts of the GO term they are applied to. Taxon constraints are used to prevent inappropriate annotations from being made by curators as well as to identify pre-existing annotations that violate the taxon constraints. Errors in annotations are automatically detected by looking for inconsistencies between the taxonomic origin of the annotated gene products and the implicit taxon specificity of the GO terms. The inconsistencies are passed on to curators for correction, in some cases the constraints need to be tightened or relaxed or the structure of the ontology needs to be adjusted. The taxon constraints are further described in this publication: Deegan, Dimmer and Mungall.

In particular, this GO reference describes the criteria used to assign evidence codes ISS, ISA, ISO, ISM, IGC and ND. To assign ISS, ISA, ISO and ISM evidence codes, SEA-PHAGE biocurators use a varied array of bioinformatics tools to establish homology and conservation of sequence and structure functional determinants with proteins from multiple organisms with published association to experimental GO terms and lacking NOT qualifiers. These proteins are referenced in the WITH field of the annotation using their xref database accession. The primary tools for homology search in ISS, ISA, ISO and ISM assignments are BLASTP and HHpred, using a maximum e-value of 10^-7 for BLASTP and a minimum probability of 0.9 for HHpred, and manual inspection of alignments in both cases. For ISS and ISA assignments, BLASTP alignments are required to have at least 75% coverage and 30% identity. For ISO assignments, orthology is further validated using reciprocal BLASTP with the identified hit. For HHpred results, ISS or ISM annotations are made only if the source for the original GO annotation explicitly defines a matched domain function, or if more than half of the domains of the query protein are identified in the matching protein. All ISS, ISA, ISO and ISM assignments entail the manual verification of the source for the GO term in the matching protein sequence and critical curator assessment of the likelihood of preservation of function, process or component in the context of bacteriophage biology. IGC codes are assigned on the basis of suggestive evidence for function based on synteny, as inferred from whole-genome comparative analyses of multiple bacteriophage genomes using primarily the Phamerator software platform, and with special emphasis on the bacteriophage virion structure and assembly genes. When extensive review of published literature on putative homologs reveals no experimental evidence of function, component or process for a particular gene product, it is assigned an ND evidence code and annotated to the root term for Cellular Component, Molecular Function and Biological Process. As part of the review process for assignment of ISS, ISA, ISO, IGC and ISM evidence codes, SEA-PHAGE curators are required to analyze the reference literature for identified matches and shall perform GO annotations with appropriate evidence codes if these were not available. diff --git a/metadata/gorefs/goref-0000101.md b/metadata/gorefs/goref-0000101.md deleted file mode 100644 index 97bac0c5..00000000 --- a/metadata/gorefs/goref-0000101.md +++ /dev/null @@ -1,10 +0,0 @@ ---- -authors: Sascha Steinbiss, GeneDB curators -id: "GO_REF:0000101" -year: 2015 -layout: goref ---- - -## Automated transfer of experimentally-verified GO annotation data to close orthologs - -This reference is used to describe functional annotations transferred from one or more reference ("source") organisms to a newly annotated ("target") organism on the basis of ortholog cluster membership.

In particular, this GO reference describes the criteria used to make annotations based on evidence codes ISS, ISA, ISO, ISM and IGC. To perform ISS-, ISA-, and ISO-based annotations on a gene product, CACAO biocurators use sequence- and structure-based search algorithms (e.g. BLASTP, HHPred) to establish homology, conservation of sequence and structure functional determinants between the target gene product and gene products from other organisms with published GO annotations supported by experimental codes and lacking NOT qualifiers. These gene products are referenced in the WITH field of the annotation using their xref database accession. ISM-based annotations make use of published computational methods (e.g. TMHMM, SignalP) to predict gene product structure, localization or function. IGC-based annotations are made on the basis of suggestive evidence for function based on synteny. Parameters and criteria for use of all computational methods (e.g. e-value) are listed and versioned in the publicly available CACAO documentation (http://gowiki.tamu.edu/).

Annotations are created when a curator judges that the sequence, composition and function of a complex shows high similarity to another complex that has annotation(s) supported by experimental evidence (and therefore display one of the evidence codes ECO:0000353 [IPI] or ECO:0005543). Annotations resulting from the transfer of GO terms display the ECO:0005610, ECO:0005544 or ECO:0005546 evidence codes and include an accession for the complex from which the annotation was projected in the 'with/from' field (column 8). This field MUST contain a Complex Portal accession identifier. Putative homologs are chosen using information combined from a variety of complementary sources. Potential homologs are initially identified using sequence similarity search programs such as BLAST. Homologous relationships are then verified manually using a combination of resources including sequence analysis tools, phylogenetic and comparative genomics databases such as Ensembl Compara, INPARANOID and OrthoMCL, as well as other specialised databases such as species-specific collections (e.g. HGNC's HCOP). In all cases curators check the alignments for each complex component and use their experience to assess whether similarity is considered to be strong enough to infer that the two proteins have a common function so that they can confidently project an annotation. While there is no fixed cut-off point in percentage sequence similarity, generally proteins which have greater than 70% identity that covers greater than 90% of the length of both proteins are examined further. Whilst we expect subunit composition to be conserved between closely related species, this is not an absolute rule and orthologous complexes may differ if a subunit cannot be traced in one species or is experimentally shown not to be present. When there is evidence of multiple paralogs for a single species, multiple variants of the complex can be inferred. diff --git a/metadata/gorefs/goref-0000115.md b/metadata/gorefs/goref-0000115.md deleted file mode 100644 index f11abf25..00000000 --- a/metadata/gorefs/goref-0000115.md +++ /dev/null @@ -1,22 +0,0 @@ ---- -authors: RNAcentral (1).
