Agenda

Ability to add comments to an annotation

We want to be able to capture why a particular experiment/result was not captured as an annotation and make this comment visible to the public. This issue came up during the April curation consistency discussion (mouse paper). I made a github ticket. https://github.com/ebi-uniprot/Protein2GO/issues/1 How should we control this field so we don't write long sentences? Limit it to 140 characters? Other ideas?

obsolete relationships

There are some relationships that were obsoleted (mostly for use with col-16). Not sure how other groups are rehousing these annotations. Instead of a regular consistency exercise is it okay if we go through some of the papers and get your input on how to rehouse those col-16 data?

Note there are also 2 relationships which have been suggested to be obsoleted: dependent on in presence of

These pages list some of the use cases and try to suggest alternative ways to capture this data. A similar approach is required for the relationships that are now obsolete.

Comments from groups re annotation

  • Ouabain plant derived drug used to treat hypotension and some arrhythmias, but also toxic.
  • We debated about annotating to sodium:potassium-exchanging ATPase activity - GO:0005391, but there is no exp. evidence to show that there was indeed exchange of these ions. There is no data for the term ATPase, coupled either. Without using background knowledge we cannot make the granular annotation based on just this paper.
  • The authors express ATP1A2 and ATP1B1. But there is not enough data in this paper to say that alpha and beta subunits contribute to the activity. So we did not capture annotations to beta subunit.
  • Normally we won't make the annotations to potassium ion binding and sodium ion binding, but if this is the only paper on this protein these annotations are acceptable
  • There is no background measurement for activity without the transfected proteins (negative control) - although there are measurements for activity of mutants which have lower activity.
  • Should there be a connection in the ontology tree between the terms ATP binding and ATPase activity.
  • Annotation to sodium:potassium-exchanging ATPase activity is necessary for annotation to complex GO:0005890 sodium:potassium-exchanging ATPase complex

ATP1A2 contributes_to drug binding GO:0008144 1/4 IPI CHEBI:472805 - ouabain take to GO meeting, this is not a normal function, do other databases capture this?
ATP1B1 contributes_to drug binding GO:0008144 1/4 IPI CHEBI:472805 - ouabain ditto
ATP1A2 contributes_to carbohydrate derivative binding GO:0097367 1/4 IPI CHEBI:472805 - ouabain this is not the function of the protein, this is an experimentally forced 'activity'
