G protein-coupled receptor (GPCR) kinases (GRKs), are important regulators of GPCR function and mediate receptor desensitization, internalization, and signaling. Several non-GPCR proteins also serve as GRK substrates, and GRKs have been shown to have kinase-independent functions through regulation of receptors and effectors. These proteins are members of the G protein-coupled receptor kinase subfamily of the Ser/Thr protein kinase family. GRKs phosphorylate activated forms of G protein-coupled receptors to regulate their signaling.
