Anti-GRK3 Antibody Picoband®

Beta-adrenergic receptor kinase 2 (beta-ARK-2), also known asG-protein-coupled receptor kinase 3 (GRK3), is anenzymethat in humans is encoded by theADRBK2gene. The humanADRBK2gene is located on 22q11. The beta-adrenergic receptor kinase specifically phosphorylates the agonist-occupied form of the beta-adrenergic and related G protein-coupled receptors. Overall, the beta adrenergic receptor kinase 2 has 85% amino acid similarity with beta adrenergic receptor kinase 1, with the protein kinase catalytic domain having 95% similarity. These data suggest the existence of a family of receptor kinases which may serve broadly to regulate receptor function.

Could induce apoptosis in a BH3 domain-dependent manner. The interaction network of Bcl-2 family members may play a key role in modulation RTL10/BOP intrinsic apoptotic signaling activity.
