Background: GRK5

G protein-coupled receptor kinases (GRKs) are important modulators of G protein-coupled receptor (GPCR) signaling. Receptor phosphorylation by specific GRKs plays a key role in triggering rapid desensitization. The GRK family consists of 7 isoforms that share a central catalytic domain with homology to other serine/threonine kinases. The catalytic domain is flanked by an amino-terminal RGS domain of 183‑188 amino acids and a carboxyl-terminus of variable length. GRK5 is a member of the GRK4 subfamily, and is expressed in a wide variety of tissues.
