General annotation (Comments)

Function

Specifically phosphorylates the activated forms of G protein-coupled receptors. Such receptor phosphorylation initiates beta-arrestin-mediated receptor desensitization, internalization, and signaling events leading to their desensitization. Seems to be involved in the desensitization of D2-like dopamin receptors in striatum and chemokine receptor CXCR4 which is critical for CXCL12-induced cell chemotaxis By similarity. Phosphorylates rhodopsin (RHO) (in vitro) and a non G-protein-coupled receptor: LRP6 during Wnt signaling (in vitro) By similarity.

Catalytic activity

ATP + [G-protein-coupled receptor] = ADP + [G-protein-coupled receptor] phosphate.

Subcellular location

Membrane; Lipid-anchor.

Tissue specificity

Widely expressed. Detectable in all brain areas examined. Ref.1

Sequence similarities

Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. GPRK subfamily.

Contains 1 AGC-kinase C-terminal domain.

Contains 1 protein kinase domain.

Contains 1 RGS domain.
