Post-translational modificationi
Proteolytic cleavage by thrombin generates a new N-terminus that functions as a tethered ligand. Also proteolytically cleaved by cathepsin CTSG. Cleavage at 41-Arg-|-Ser-42 by CTSG results in receptor activation while cleavage at 55-Phe-|-Trp-56 results in inhibition of receptor activation.By similarity
Phosphorylated in the C-terminal tail; probably mediating desensitization prior to the uncoupling and internalization of the receptor.By similarity
