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 dopamine 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. Ref.4 Ref.5 Ref.6

Catalytic activity

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

Subcellular location

Membrane; Lipid-anchor.

Tissue specificity

Expressed in the brain in striatal neurons. Ref.6

Disruption phenotype

Deficient mice show significant altered central dopamine receptors regulation, deficient lymphocyte chemotaxis and increased acute inflammation and neutrophil chemotaxis. Ref.4 Ref.5 Ref.6

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.
