Modification Annotation

Modifications are annotated in Canto on the gene product which is being modified (i.e the modified target).

Annotation extensions and qualifiers can be used to capture additional supporting data described below

Capturing Information about the modifier, or temporal features of the modification

Usage Relation Syntax (Example) Notes
data shows the identity of the modifieradded_by added_by(wee1) ensure that you have annotated the modifier with the molecular fiunction and substrate
data shows identity of modification removerremoved_by removed_by(cdc25)ensure that you have annotated the modifier with the molecular fiunction and substrate
data shows "active" addition at a certain timeadded_during removed_during(GO:0000080)GO IDs are phases which are stored in the BP ontology
data shows "active" addition at a certain timeremoved_during removed_during(GO:0000080) -

Capturing information about the modified residue(s)

Syntax for capturing the modified residue(s)

  • residue=S204
  • residue=S204|S205|T206 *Question IS THIS CORRECT???
  • the residues numbers apply to the mature form of the protein, not the precursor translation, (NOTE THIS PAGE SAYS UNMODIFIED EXCEPT HISTONES describing residues modified or mutated
  • make sure that you request a pro ID for the shorter form, and put this in an annotation_extension has_direct_input(PR:xxxxx) so that the residues you specify matches the molecule in this extension.

Detiled syntax for compound vs. independent annotations =

I DON"T UNDERSTSTAND THIS COMMENT For annotations which involve a "target gene" of this type which are not "protein modification" annotations we only capture the target gene as an annotation extension, and the reciprocal annotation (gene B is TARGET_OF Gene A) will be inferred later
