Molecular function

Binding to a protein upon phosphorylation of the target protein.

This term should only be used when the binding is shown to require phosphorylation of the target protein: the interaction needs to be tested with and without the PTM. The binding does not need to be at the site of phosphorylation. It may be that the phosphorylation causes a conformational change that allows binding of the protein to another region; this type of phosphorylation-dependent protein binding is valid for annotation to this term.
