Detection of Human GRK3 by Western Blot. Western blot shows lysates of Jurkat human acute T cell leukemia cell line and CEM human T-lymphoblastoid cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human GRK3 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4785) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for GRK3 at approximately 80 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

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. GRK3 (also known as beta -adrenergic receptor kinase 2, or beta ARK2) and GRK2 ( beta ARK1) are members of the beta -adrenergic receptor kinase subfamily. GRK3 may phosphorylate alpha -synuclein at S129, suggesting a potential involvement for this kinase in Parkinson’s disease.
