Annotation Practices

1. When annotating to Cellular Component terms:

If a protein contains a transmembrane domain, but expression experiments are not at sufficient resolution to show membrane localization, what annotation should we make?

Example: WBPaper00036024

Plans/Projects in progress

Changes to the GO data model

  • Add tags for accommodating data in WormBase that are already in the gene association file:
    • Qualifying an annotation with the qualifiers 'NOT' 'contributes_to' or 'colocalizes with'
    • Using the generic GO_REF tags for generic references eg., for a NOT annotation, need to add the the proper database and accession syntax
    • 'With' or 'From', for the use of additional identifiers with the use of certain evidence codes like IPI, IGI, etc.
    • Annotation Extension, for containing cross references to other ontologies,one of:
      • DB:gene_id
      • DB:sequence_id
      • CHEBI:CHEBI_id
      • Cell Type Ontology:CL_id
      • GO:GO_id
    • Gene Product Form ID, a canonical entry for specific variants of gene products.
      • When the gene product form ID (column 17) is filled with a protein identifier, the value in DB object type (column 12 of ga) must be protein. Protein identifiers can include UniProtKB accession numbers, NCBI NP identifiers or Protein Ontology (PRO) identifiers.
      • When the gene product form ID (column 17) is filled with a functional RNA identifier, the DB object type (column 12 of ga) must be either ncRNA, rRNA, tRNA, snRNA, or snoRNA.
