Protein

G protein-coupled receptor kinase 5

Gene
Grk5, Gprk5
Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Serine/threonine kinase that phosphorylates preferentially the activated forms of a variety of G-protein-coupled receptors (GPCRs). Such receptor phosphorylation initiates beta-arrestin-mediated receptor desensitization, internalization, and signaling events leading to their down-regulation. Phosphorylates a variety of GPCRs, including adrenergic receptors, muscarinic acetylcholine receptors (more specifically Gi-coupled M2/M4 subtypes), dopamine receptors and opioid receptors. In addition to GPCRs, also phosphorylates various substrates: Hsc70-interacting protein/ST13, TP53/p53, HDAC5, and arrestin-1/ARRB1. Phosphorylation of ARRB1 by GRK5 inhibits G-protein independent MAPK1/MAPK3 signaling downstream of 5HT4-receptors. Phosphorylation of HDAC5, a repressor of myocyte enhancer factor 2 (MEF2) leading to nuclear export of HDAC5 and allowing MEF2-mediated transcription. Phosphorylation of TP53/p53, a crucial tumor suppressor, inhibits TP53/p53-mediated apoptosis. Phosphorylation of ST13 regulates internalization of the chemokine receptor. Phosphorylates rhodopsin (RHO) (in vitro) and a non G-protein-coupled receptor, LRP6 during Wnt signaling (in vitro).4 Publications

Catalytic activityi

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

Enzyme regulationi

Inhibited by calmodulin with an IC50 of 50 nM. Calmodulin inhibits GRK5 association with receptor and phospholipid By similarity.

Pathology & Biotechi

Disruption phenotypei

No obvious phenotype due to the redundancy of GRK subtypes in the regulation of GPCR signaling. Deficient mice are viable and showed no anatomic or behavioral abnormalities, only a slight decrease in body temperature. However deficient mice shown altered central and lung M2 muscarinic receptor regulation, with normal heart M2 receptor regulation. GRK5 deficiency leads to a reduced hippocampal acetylcholine release and cholinergic hypofunction by selective impairment of desensitization of presynaptic M2/M4 autoreceptors and promotes beta-amyloid accumulation.4 Publications
