No call next week - No GO Calls Week


Follow up: Cellular Component, ShEx, and GO-CAMs -- BLOCKING FOR GO-CAM

  • The ShEx specifications state that MFs can occur in an Anatomical Entity and that GPs or Protein-Containing Complexes can be located in an Anatomical Entity.
  • Most non-protein-containing complex GO CC terms are a child of Cellular Anatomical Entity which is a subclass of Anatomical Entity.
  • However, annotations to root Cellular Component result in ShEx violations because root Cellular Component is NOT a subclass of Anatomical Entity.


  • Chris: suggests keeping the current practice and use root Cellular Component and ND.
  • Action would be to change the ShEX to allow a direct annotation to occurs_is/is active in root Cellular Component

Is this still OK?

  • Need to look at ShEx with Jim

'process has causal agent' relation

Raymond proposed to use in LD: https://github.com/geneontology/go-ontology/issues/13307#issuecomment-786985814

extrasynaptic signalling via GABA 'cell-cell signaling' and ('process has causal agent' some 'gamma-aminobutyric acid zwitterion') and ('occurs in' some 'perisynaptic space')

  • See proposal in ticket

New relationships after using equivalent Rhea reaction


Jim generated a ttl file.


  • Created Logical definition
  • Plan: going forward, creating new terms:
    • add Rhea description in textual definition
    • bring EC mapping from Rhea
    • pull EC name automatically
    • retrospectively  ??''
  • Next step:
    • check if those logical definitions cause problems in inferences
    • Jim to check if some subsumptions are missing

id ranges file


  • do we need "The Original Set (OS) of GO terms"
  • do we need both the text and owl files?
