'''''Changes to SPKW2GO and SPSL2GO'''''
With the aid of Serenella Ferro-Rojas, the SPKW2GO and SPSL2GO mappings have been revised - so far 70 mappings have been added to the SPSL2GO mapping, as well as changes to 24 different SPK2GO mappings since March 2009.

Annotation Progress

We continue to put emphasis on the annotation of those genes selected for the Reference Genome Project.

In addition, with the newly started kidney-centric annotation project, additional emphasis has been placed on certain genes associated with renal development and disease.


GOA UniProt gene association file release stats (comparison of March 09 and September 2009 releases)

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:

GOA provides IEA annotations from the following methods:

  1. Swiss-Prot Keyword 2GO (SPKW2GO)1,2
  2. Swiss-Prot Subcellular Locations2GO (SPSL2GO) 1,2
  3. HAMAP2GO2
  4. InterPro2GO2
  5. EC2GO2
  6. Ensembl Compara

Legend

1: mapping tables created and maintained by the GOA group

2: electronic annotations generated by the GOA group, using UniProtKB.


  1. Priorities for annotation
  1. Genes assigned by Reference Genome Project (Rachael, Emily)
  2. Genes associated with renal processes (Yasmin)
  3. Requests from user community (all curators)
  4. Proteins annotated during Swiss-Prot curation duties (all Swiss-Prot curators at the EBI and SIB)

Other Highlights

New staff:

Yasmin Alam-Faruque

Tony Sawford

A. Ontology Development Contributions:

100 SourceForge items regarding requested changes to the GO have been placed by curators associated with the GOA group since March 2009


B. Annotation Outreach and User Advocacy Efforts:

GOA is currently training curators at the Swiss Institute of Bioinformatics. Rachael and Emily have been travelling to Geneva on the to train Swiss-Prot curators. Rachael and Emily then checked all annotations generated by this group over the following 2 months before making the annotations public. The Swiss-Prot team in Geneva have so far generated approximately x,000 manual GO annotations. Annotations are created in GOA's protein2go tool, and released in the groups gene association files. Such annotations use the existing source 'UniProtKB' (for column 15 of the gene association file).

GOA will continue to train and mentor SIB curators over 2009 and 2010.

Changes to SPKW2GO and SPSL2GO With the aid of Serenella Ferro-Rojas, the SPKW2GO and SPSL2GO mappings have been revised - so far 70 mappings have been added to the SPSL2GO mapping, as well as changes to 24 different SPK2GO mappings since March 2009.


Renal GO annotation initiative funded by Kidney Research UK.

This grant started on the 1st April, managed by Yasmin Alam-Faruque, who joined GOA from the Swiss-Prot team at the EBI.

Aim 1: Promote wider scientific engagement in GO annotation through a variety of outreach efforts • Generated web pages providing further information about the Renal GOA Initiative: http://www.ebi.ac.uk/GOA/kidney/ and http://www.geneontology.org/GO.renal.shtml. • Set up the Renal Interest Group mailing list on the Gene Ontology Consortium web pages: http://www.geneontology.org/GO.interests.shtml?all#renal (aimed at encouraging researchers to provide suggestions/ advice/ discussions on renal gene/ protein-related issues) • Two quarterly newsletters have been circulated, which provide further information on the project’s progress: http://www.ebi.ac.uk/GOA/kidney/newsletter/.

Aim 2: Annotate gene products associated with kidney development and disease • In collaboration with members of the Scientific Advisory Panel, a list of renal-related proteins has been created which act as an initial set of curation targets, available from: http://www.ebi.ac.uk/GOA/kidney/. Initial annotation targets were highly investigated proteins involved in the proton pump process and ammonium transport; both processes being important for the maintenance of acid-base homeostasis in the kidney. Additional targets have been provided by the GUDMAP Consortium, which have no current GO annotations. • To date this initiative has created 1,885 GO annotations to 387 UniProtKB protein accessions; this figure exceeds stated annotation targets in the grant proposal • Annotations to this list are publicly available from QuickGO browser (http://www.ebi.ac.uk/QuickGO/GAnnotation?protein=KRUK). - enabling members of the biomedical research community to search and view the dataset easily in the GOA group’s QuickGO browser • Collaboration initiated with the Reactome group, resulting in further members of the solute-carrier transmembrane transporter protein superfamily added to the Reactome database. This is going to be expanded to other transmembrane transporter protein families including the proton pump, ion channels and aquaporins. The inclusion of more proteins involved in renal-specific processes into the Reactome database will provide an even more unique and comprehensively detailed functional dataset for mammalian gene products implicated in renal function and development. • A co-annotation project has been initiated with other curators to improve annotation of proteins involved in the development and function of the Loop-of-Henle structure for mammalian and non-mammalian organisms . This will highlight not only biological insights into the similarities and differences of the orthologous genes in distinct species, but also demonstrate the usefulness of focused, collaborative cross-species GO annotation by demonstrating to users the usefulness of functional annotation. This effort will also lead to focused development of GO terms to more accurately describe renal-associated processes. An envisaged publication on such a study would provide publicity to the renal annotation initiative and other databases.


Aim 3: Improve the Gene Ontology with respect to Renal Processes • Collaboration initiated with the GUDMAP Consortium. This effort is reviewing the state of renal GO terms that currently exist in the ontology (initially with respect to nephrogenesis) and hence develop and improve GO terms in-line with the kidney anatomy work carried out by the renal community


Gene Association File changes


July 2009 Previously, annotation lines produced by electronic methods (as indicated by the presence of the 'IEA' evidence code in column 7) contained two identifiers piped together in the reference column; an internal GOA keyword (e.g. GOA:interpro) and a GO reference identifier (e.g. GO_REF:0000002). As of this fille release, the GOA internal reference (e.g. GOA:interpro) and pipe has been removed from this field, so that only a GO_REF identifier is provided.

May 2009 DB field (column 1). Column 1 of the gene association file is used to identify the database which has supplied the sequence identifier displayed in column 2. Its value is very often 'UniProtKB'. However recent changes to other fields in the GOA gene association files have made it difficult for users to identify whether an UniProtKB accession originates from the UniProtKB/Swiss-Prot or UniProtKB/TrEMBL databases. Therefore it is intended that when a UniProtKB accession is provided in column 2, column 1 will in future display either 'UniProtKB/Swiss-Prot' or 'UniProtKB/TrEMBL'.
