Rabbit anti GRK2 antibody
recognizes beta-adrenergic receptor kinase 1, also known as ADRBK1, BARK or BARK1. It belongs to the family of serine/threonine protein kinases called GPCR kinases (GRKs) that phosphorylate agonist occupied receptors (Pitcher et al. 1998
). PKC-mediated phosphorylation of GRK2 increases activity toward its substrates (Krasel et al. 2001
). GRK2 mediates ERK activation downstream of the EGFR by acting as a Rho-activated scaffold protein (Robinson and Pitcher 2013
). As GRK2 can modulate several hallmarks of cancer by participation in many signaling pathways, it was suggested that it acts as an oncomodifier (Nogues et al. 2017
