Also there were improvements made to renal physiology terms describing diuresis and natriuresis in response to a SourceForge request made by Cynthia Smith [https://sourceforge.net/tracker/index.php?func=detail&aid=3202051&group_id=36855&atid=440764]. This was done in close collaboration with renal experts via a webex conference call and a face-to-face meeting with them. It was decided to delete the existing terms  ''diuresis ; GO:0030146''  The process of renal water excretion  and ''natriuresis ; GO:0030147''  The process of renal sodium excretion  and to replace them with ''positive regulation of urine volume ; GO:NEW'' to describe diuresis and ''positive regulation of renal sodium excretion ; GO:NEW'' to describe natriuresis.

===Protein2GO curation tool===
 
A new version of the Protein2GO tool was released to all curators in October. With a number of changes to improve the layout of the annotations displayed, improved display of controls for updating or transferring new annotations and greater integration of term-specific link outs to the QuickGO Ancestor Chart.
* Improvements to the co-occurring terms table, including further explantation
 
* Improvements to the term search results display (obsolete term, synonym and defintion views)
 
'''March 2011'''
* Improvements to support developing user-defined GO slims via the 'Your Terms' basket.
 
* There is now the option, within the Ancestor Chart, to show the direct child terms of the term being viewed. When viewing your chosen term in the Ancestor Chart display, click on 'Display' on the right of the page and change the 'show children' option from the default 'Hide' to 'Show', click on OK and the Ancestor Chart will display all of the direct child terms for the term you are viewing.
 
* The display of the has_part relationship in the Ancestor Chart has been adjusted to highlight that this relationship should be read in the opposite direction to the other relationships.  


*QuickGO now provides links to the IntAct interaction database from GO protein complex term pages. For example, see 'septin complex' which links out to the curated protein complex in IntAct.
Link out to the IntAct editor are available to IntAct-trained curators.


* The ancestor table view from the GO term page has been removed as we felt this is a confusing view of the ancestry of a GO term and can sometimes be inaccurate in its representation. The ancestor chart view will remain.
New sanity checks have been included to reduce redundancy in annotation and to warn curators when inferred GO annotations could be created to an annotation set.


* The 'goslim_goa' predefined GO term set has been removed. It was felt that this term set now provides an inadequate top-level representation of the GO ontologies that could provide users with misleading results. A good alternative GO term set to use is the 'goslim_generic', which has recently been updated and refined to give a good coverage of general biological features within the Biological Process and Cellular Component ontologies.
In addition, the tool now provides the ability for full-time GO curators to contribute to the annotation extension field (column 16); this is optionally displayed and will be automatically suppressed for all UniProt curators unless there is specific interest.  


===Changes to UniProtKB GOA gene association files===
===Changes to UniProtKB GOA gene association files===


''May 2011''
August 2011
From the August release, the UniProt GO annotation files contained a greatly reduced number of protein binding GO annotations from the IntAct database.


UniProtKB-GOA now incorporates annotations from external groups that use a GO reference (GO_REF) or a MOD-specific reference that can be converted to an equivalent GO_REF using the mappings defined in http://www.geneontology.org/doc/GO.references in their reference field. Previously, UniProtKB-GOA only accepted annotations that used a PubMed identifier in this field.
A subset of presumed reliable interactions is now extracted from the IntAct dataset with export determined using a simple scoring system developed by IntAct, coupled to a score threshold that has been deliberately chosen to exclude interactions supported by only one experimental observation. Further details of how interactions are scored can be found at the IntAct website (http://www.ebi.ac.uk/intact/pages/faq/faq.xhtml#4). This simple score-based filter is used in combination with a set of defined rules that excludes certain types of data, such as interactions that have been inferred but not experimentally proven.


An example of a GO_REF that we are now accepting is GO_REF:0000015 'Use of the 'No biological data' (ND) evidence code for Gene Ontology terms'.
UniProtKB-GOA are pleased to announce the inclusion in their database of electronic GO annotations created by EnsemblPlants/Gramene. The annotations are created by projection of GO annotations from Arabidopsis thaliana or Oryza sativa proteins onto proteins from one or more target species based on gene orthology obtained from Ensembl Compara. This first release contains almost 230,000 annotations to over 50,000 proteins covering 16 taxonomies including; poplar, maize, sorghum, grape and Physcomitrella. We hope this will be a valuable resource for the non-model plant species community. The annotations can be viewed and downloaded from the QuickGO browser here.  
A description and complete list of the GO_REFs available can be found at http://www.geneontology.org/cgi-bin/references.cgi.  


''April 2011''

1. With the imminent closure of the International Protein Index (IPI), the Human, Mouse, Rat, Zebrafish, Chicken and Cow UniProt GO annotation files (files named: gene_association.goa_[species], e.g., gene_association.goa_human) now uses UniProt Complete Proteome sets to determine the protein composition of these files.


The Annotation Extension field (column 16) has been populated with the MGI data describing the cellular context of a GO annotation (using the Cell Type ontology)
This change has had a dramatic affect on the gene_association.goa_human file, which has increased in annotation count by 43.7% , as the file now includes GO annotations both to reviewed (Swiss-Prot) and unreviewed (TrEMBL) UniProtKB accessions. Any user wishing to only identify the reviewed (Swiss-Prot) UniProt protein annotation subset will be able continue to do so using the information supplied in the gp_information.goa_uniprot file, which can be found here.
Alternatively, users can download the reviewed UniProtKB human GO annotation set from the UniProt QuickGO browser using this link.


Over the last month we have been working to provide a more complete display of the manual annotations that we integrate into the UniProtKB-GOA dataset from external annotation groups. Whereas previously the 'with' field (column 8) in our annotation file was left empty if a manual annotation did not include either UniProtKB or GO identifier, our files now displays 43 different gene, protein and chemical identifier types (such as WormBase, CHEBI and EcoCyc identifiers) in this field. This development ensures that integrated manual GO annotations display with the full set of information that curation groups have used when translating experimental data into a GO annotation.
3. Species-specific UniProt GO annotation gene association files that include a filtering step to remove redundant electronic GO annotation predictions are now available from the GOA ftp site for the UniProt Complete Proteome sets of Dictyostellium discoideum (gene_association.goa_dicty.gz), Canis familiaris (gene_association.goa_dog.gz), Drosophila melanogaster (gene_association.goa_fly.gz), Caenorhabditis elegans (gene_association.goa_worm.gz), Saccharomyces cerevisiae (gene_association.goa_yeast) and Sus scrofa (gene_association.goa_pig.gz).  


The UniProtKB-GOA files also now contain a larger set of the manual annotations supplied by the GO Consortium's Reference Genome project (source: RefGenome). This project has generated inferred annotations for 47 species using GO Consortium manual annotations and phylogenetic trees from gene families. The Reference Genome project is fully described here: http://www.geneontology.org/GO.refgenome.shtml.  
June 2011
Inferred Cellular Component GO annotations now included in the UniProtKB-GOA annotation set.


We are pleased to announce an additional set of Cellular Component GO annotations available in this release that have been automatically generated from the 'occurs_in' relationship, made available as intersection tags in Biological Process terms in the GO OBO v1.2 format.


''February 2011''
For example:


Inferred Biological Process GO annotations now included in the UniProtKB-GOA annotation set.
[Term]
id: GO:0033579 ! protein amino acid galactosylation in endoplasmic reticulum
intersection_of: GO:0042125 ! protein amino acid galactosylation
intersection_of: occurs_in GO:0005783 ! endoplasmic reticulum


We are pleased to announce an additional set of GO annotations available in this release that have been automatically generated from the Molecular Function (MF) -> Biological Process (BP) inter-ontology relationships present in the GO OBO v1.2 format.
2. Annotations that apply the new manual GO evidence codes IBA, IBD, IKR and IRD are now available in the UniProtKB-GOA annotation set.
For further information on these recently created manual evidence codes, please consult the GO website for code definitions: http://www.geneontology.org/GO.evidence.shtml. These types of evidenced GO annotations are currently being created by the GO Consortium's Reference Genome project, identified by the 'RefGenome' value in the assigned_by field (column 15).


As many GO users do not currently reason over the GO inter-ontology relationships, a set of inferred annotations has been generated to improve the consistency of the Biological Process annotation set. These GO annotations are produced when an annotation has been made (either manually or electronically) to a Molecular Function term that, either directly or via one of its parent terms, has a relationship to a Biological Process term and where the Process term (or one of its children) has not already been used in the annotation set for the same gene product identifier. This inferred annotation set applies the same gene product identifier, reference and evidence code as the asserted function annotation and are generated from all sources of GO annotations, with only 'NOT'-qualified annotations being excluded. All such inferred GO annotations can be identified by the 'GOC' value in the 'assigned_by' field (column 15).

Annotation Progress

All curators from the different UniProt teams (based at the EBI and SIB) use the web-based Protein2GO editor maintained and developed by the UniProtKB-GOA team.

In total the UniProt group has provided 387,667 taxonomic groups with GO annotation. Since September 2010 UniProtKB curators from the EBI and SIB locations have together contributed 21,954 manual GO annotations since May 2011.

Currently the curators from the GOA and BHF-UCL projects have together completely annotated 76% of supplied human Reference Genome Targets.

Methods and strategies for annotation

  1. Literature curation:

Literature curation continues to be the major focus of our annotation efforts, with an emphasis on the use of experimental evidence codes.


  1. Computational annotation strategies:

UniProtKB provides IEA annotations using the following methods that use information extracted from UniProtKB, InterPro, the GO ontology, Ensembl and EnsemblCompara:

  1. UniProtKB Keyword 2GO (SPKW2GO)1,2
  2. UniProtKB Subcellular Locations2GO (SPSL2GO) 1,2
  3. HAMAP2GO2
  4. InterPro2GO2
  5. EC2GO2
  6. Ensembl Compara
  7. EnsemblGenomes Compara

Legend

1: mapping tables created and maintained by the UniProtKB group

2: electronic annotations generated by the UniProtKB group, using external resources combined with UniProtKB annotations.

  1. Priorities for annotation

UniProtKB curators annotate inline with UniProtKB priorities and curate to GO while carrying out UniProtKB annotation work.

The table showing the species prioritised for annotation is displayed below. This is in addition to the annotation projects involving animal toxins, submissions, proteins with 3D structures, enzymes, post-translational modifications. A number of these projects have required substantial work into developing appropriate GO Terms.

The curators in the UniProtKB-GOA team continue to put emphasis on the annotation of those genes selected for the Reference Genome Project, user-feedback as well as annotations for the grant deliverables from British Heart Foundation and Kidney Research UK funding.

Other Highlights

A. Ontology Development Contributions:

Terms and content meeting organisation to improve the Apoptosis node.

Creation of a new external2GO mapping file that uses the UniPathway resource is continuing and requiring GO content development effort as currently 366 UniPathway terms do not have an equivalent in GO e.g. palmatine biosynthesis

The development of new terms relating to aspects of kidney development is ongoing with the creation of a further X terms created earlier this year bringing the total number of kidney development terms to X (from xxx last year). The total list of terms can viewed at [1].

B. Annotation Outreach and User Advocacy Efforts:

dictyBase Curators manually annotating to GO in the dictyBase group have been moved across to using UniProtKB's GO curation tool: Protein2GO. UniProtKB-GOA now generates a gene association file for Dictyostellium that dictyBase will modify and enhance for their user community.

Verification of mappings to UniProtKB accessions in GO Consortium gp2protein files

The GOA group continues to provide groups in the GO Consortium with checks of the UniProtKB accessions applied in gp2protein mapping files. Annotation groups receive an email to indicate where in their file a secondary or deleted UniProtKB has been used. This email also (where possible) indicates suitable replacement UniProtKB accessions. Such checks are run and results emailed to annotation groups on the first of each month.

Protein2GO curation tool

A new version of the Protein2GO tool was released to all curators in October. With a number of changes to improve the layout of the annotations displayed, improved display of controls for updating or transferring new annotations and greater integration of term-specific link outs to the QuickGO Ancestor Chart.

Link out to the IntAct editor are available to IntAct-trained curators.

In addition, the tool now provides the ability for full-time GO curators to contribute to the annotation extension field (column 16); this is optionally displayed and will be automatically suppressed for all UniProt curators unless there is specific interest.

Changes to UniProtKB GOA gene association files

August 2011 From the August release, the UniProt GO annotation files contained a greatly reduced number of protein binding GO annotations from the IntAct database.

A subset of presumed reliable interactions is now extracted from the IntAct dataset with export determined using a simple scoring system developed by IntAct, coupled to a score threshold that has been deliberately chosen to exclude interactions supported by only one experimental observation.

July 2011 1. With the imminent closure of the International Protein Index (IPI), the Human, Mouse, Rat, Zebrafish, Chicken and Cow UniProt GO annotation files (files named: gene_association.goa_[species], e.g., gene_association.goa_human) now uses UniProt Complete Proteome sets to determine the protein composition of these files.

This change has had a dramatic affect on the gene_association.goa_human file, which has increased in annotation count by 43.7% , as the file now includes GO annotations both to reviewed (Swiss-Prot) and unreviewed (TrEMBL) UniProtKB accessions. Any user wishing to only identify the reviewed (Swiss-Prot) UniProt protein annotation subset will be able continue to do so using the information supplied in the gp_information.goa_uniprot file, which can be found here. Alternatively, users can download the reviewed UniProtKB human GO annotation set from the UniProt QuickGO browser using this link.

3. Species-specific UniProt GO annotation gene association files that include a filtering step to remove redundant electronic GO annotation predictions are now available from the GOA ftp site for the UniProt Complete Proteome sets of Dictyostellium discoideum (gene_association.goa_dicty.gz), Canis familiaris (gene_association.goa_dog.gz), Drosophila melanogaster (gene_association.goa_fly.gz), Caenorhabditis elegans (gene_association.goa_worm.gz), Saccharomyces cerevisiae (gene_association.goa_yeast) and Sus scrofa (gene_association.goa_pig.gz).

June 2011 Inferred Cellular Component GO annotations now included in the UniProtKB-GOA annotation set.

We are pleased to announce an additional set of Cellular Component GO annotations available in this release that have been automatically generated from the 'occurs_in' relationship, made available as intersection tags in Biological Process terms in the GO OBO v1.2 format.

For example:

[Term] id: GO:0033579 ! protein amino acid galactosylation in endoplasmic reticulum intersection_of: GO:0042125 ! protein amino acid galactosylation intersection_of: occurs_in GO:0005783 ! endoplasmic reticulum

2. Annotations that apply the new manual GO evidence codes IBA, IBD, IKR and IRD are now available in the UniProtKB-GOA annotation set. For further information on these recently created manual evidence codes, please consult the GO website for code definitions: http://www.geneontology.org/GO.evidence.shtml. These types of evidenced GO annotations are currently being created by the GO Consortium's Reference Genome project, identified by the 'RefGenome' value in the assigned_by field (column 15).
