ADRBK1 (GRK2) is a serine/threonine kinase. Many of the G protein-coupled receptors are known to be phosphorylated by G protein-dependent receptor kinases (GRKs). G protein-coupled receptor kinases (GRKs) are important regulators of G protein-coupled receptors(GPCRs). GRK2 (83 kDa), one of six members of this family that have been identified, is ubiquitously expressed in mammals. After binding to their ligand and interacting with heterotrimeric G proteins, GPCRs (e.g., a2-adrenergic receptor) are phosphorylated by GRKs. Internalization of the GPCRs, regulated by beta-arrestin-1, leads to activation of the Ras - Raf - ERK1&2 signaling pathway. GRK2 activity is tightly controlled by different mechanisms including phosphorylation by kinases such as PKC, Src and ERK1&2, as well as interaction with various proteins. ERK phosphorylates and thus inactivates GRK2 on serine 670 in a negative feedback mechanism.
