Adrenergic Receptor Kinase, beta 1 (bARK1, B1 AR, ARK1 beta, G Protein Coupled Receptor Kinase 2, GPCR K2, GRK2)
Description:
Beta-adrenergic receptor kinase (ADRBK1) phosphorylates the beta-2-adrenergic receptor and appears to mediate agonist-specific desensitization observed at high agonist concentrations. ADRBK1 is an ubiquitous cytosolic enzyme that specifically phosphorylates the activated form of the beta-adrenergic and related G-protein-coupled receptors. The ADRBK1 gene spans approximately 23 kb and is composed of 21 exons. Heart failure is accompanied by severely impaired beta-adrenergic receptor (beta-AR) function. An important mechanism for the rapid desensitization of beta-AR function is agonist-stimulated receptor phosphorylation by the beta-AR kinase (beta-ARK1), an enzyme known to be elevated in failing human heart tissue. Abnormal coupling of beta-adrenergic receptor to G protein is involved in the pathogenesis of the failing heart. Inhibition of ADRBK1 is a novel mode of therapy.

Positive Control: Daudi cell lysate

Applications:
Suitable for use in ELISA and Western Blot. Other applications not tested.

Recommended Dilution:
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot Store at -20C. Aliquots are stable for at least 12 months at -20C. 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.
