How to represent that phosphorylation of a protein activates it?

[cthoyt]

In BEL, it's common to see chains like:

# protein X phosphorylates protein Y
act(protein(X)) -> protein(Y, pmod(Ph))

# protein Y becomes active when it's phosphorylated (the part I'm actually asking about)
protein(Y, pmod(Ph)) -> act(protein(Y))

# Phosphorylated protein Y (active) phosphorylates protein Z
act(protein(Y)) -> protein(Z, pmod(Ph))

I apologize if this isn't idiomatic, but I hope it gets the idea across. What would be the best relation / set of relationships to express this using RO?

Is there a BEL toolkit for interconverting between these?

presumably another way is

act(p(X), ma(GO:"kinase activity")) -> act(protein(Y))

This would have the most natural mapping to an activity-centric GO-CAM view. Here the semantics are on the occurrent class, and a more general directly activates relation could be used

@goodb, is the inference of the modifications something that could fall out of the RHEA axiomatization work?

I'm not seeing how the RHEA work would impact this, but might be missing something. Could you give a strawman of what you are thinking might be working here - in terms of the GO MF definitions? The RHEA-based axiomitization of catalytic activities will be useful for classification based on the inputs and outputs of a reaction/function. (See https://github.com/geneontology/go-ontology/issues/14984 ).

Is this still needed?

[cthoyt]

This is still unresolved. #522 will hopefully renew interest in this
