Synonyms G protein-coupled receptor kinase GRK4, ITI1 | GPRK2L, GPRK4
Primary ID P32298

Type protein
Relations 3
Function Specifically phosphorylates the activated forms of G protein-coupled receptors. GRK4-alpha can phosphorylate rhodopsin and its activity is inhibited by calmodulin; the other three isoforms do not phosphorylate rhodopsin and do not interact with calmodulin. GRK4-alpha and GRK4-gamma phosphorylate DRD3. Phosphorylates ADRB2.
