Adult rat brain membrane (RBM) and transfected cell immunoblot: extracts of RBM and COS cells transiently transfected with untagged GRK5, GRK6 and Kv2.1 plasmids and probed with N142/28 TC supe.
G-protein coupled receptor kinase 6 is encoded by the gene GRK6. GRK6 is a member of the protein kinase superfamily, AGC Ser/Thr protein kinase family, GPRK subfamily. GRK6 phosphorylates the activated forms of G-protein coupled receptors, thus initiating their deactivation. GRK6 is expressed in the brain in striatal neurons and spleen. No disorders were found to be associated with GRK6.
Fusion protein amino acids 371-576 (C-terminus) of mouse GRK6A(also known as G protein-coupled receptor kinase 6A and Gprk6A, accession number O70293); Rat: 98% identity (203/206 amino acids identical); Human: 95% identity (197/206 amino acids identical); 100% identity with GRK6B (189/189 amino acids identical, amino acids 371-559); Greater than 55% identity with GRK5 and GRK4
Store at ≤ -20 C for long term storage. For short term storage, store at 2-8 C. For maximum recovery of product, centrifuge the vial prior to removing the cap.
