Anti-Adrenergic Receptor Kinase, beta 1 (bARK1, B1 AR, ARK1 beta, G Protein Coupled Receptor Kinase

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. GRK2 is a member of the BetaARK subfamily, and was originally termed Beta-adrenergic receptor kinase 1 (BetaARK1). Applications: Suitable for use in Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 1ug/ml, Optimal dilutions to be determined by the researcher. Storage and Stability: Lyophilized powder may be stored at -20°C. Reconstitute to nominal volume by adding sterile 40-50% glycerol, aliquot and store at -20°C. Reconstituted product is stable for 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
