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.

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)

A. Ontology Development Contributions:

x GO terms have been created during annotation efforts by the group


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.

C. Other


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. PROGRESS REPORT

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'.
