PAINT software

  • hoping to have it available for this round of annotation
  • pulling data from the GO database (annotations)
  • need to write a GAF file

Next electronic jamboree Feb24

Please annotate genes !! Electronic_jamboree_feb24-2009


Annotation Issues

PAINT annotations: ISS

  • PAINT annotations are done in two steps:
    1. Annotating the common ancestor (hypothetical protein) by ISS by 'tree annotators'
    2. This generates a GAF file that can be used to propagate those annotations to all other descendants of that sequence
  • In both cases, the annotation uses ISS as evidence code. OK?

Qualifiers

  • Are they being used consistently and can we use them for propagation?

Contributes_to

  • Used with two different meanings: (1) when a multisubunit complex needs two or more gene products for activity, and (2) from documentation: "Note that contributes_to is not needed to annotate a catalytic subunit. Furthermore, contributes_to may be used for any non-catalytic subunit, whether the subunit is essential for the activity of the complex or not." [1]
  • This last statement should be removed. It's incorrect to annotate a function as if annotating a component.
  • contributes_to for RG genes (txt); File:Contributes to RG-2009-02.xls (xls)as of Feb 9, 2009:

Colocalizes with

  • Used with two different meanings: (1) transient localization, and (2) peripheral association.
    • Do we need to annotate peripheral associations? If the assay cannot resolve the component, should we not annotate to the parent?
    • If we mean 'transient', should the qualifier be 'transiently localized' (ie, more explicitly saying what we're trying to capture?
  • colocalizes_with for RG genes (txt); File:Colocalizes with RG-2009-02.xls (xls) as of Feb 9, 2009.

Fraction terms

  • From the TOP2 curation [[2]] : Should Fraction terms be obsoleted? Sine they do not represent cellular components? If people agree here, we can ask the GO/annotation lists.
  • GO:0001950 : PME fraction
  • GO:0000267 : cell fraction
  • GO:0005625 : soluble fraction
  • GO:0005624 : membrane fraction
  • GO:0005626 : insoluble fraction
  • GO:0042598 : vesicular fraction
  • GO:0000299 : integral to membrane of membrane fraction
  • GO:0000300 : peripheral to membrane of membrane fraction

Next conference call

Tuesday March 10, 2009, 11 AM PDT, 1 PM CDT, 2 PM EST, 7 PM BST
