Beta Arrestin 1 is a protein which in humans is encoded by the ARRB1 gene. Members of arrestin/beta-arrestin protein family are though to participate in agonist-mediated desensitization of G-protein-coupled receptors and cause specific dampening of cellular responses to stimuli such as hormones, neurotransmitters, or sensory signals. By fluorescence in situ hybridization,this gene is mapped to 11q13.4. Beta Arrestin 1 is a cytosolic protein and acts as a cofactor in the beta-adrenergic receptor kinase (BARK) mediated desensitization of beta-adrenergic receptors. Besides the central nervous system, it is expressed at high levels in peripheral blood leukocytes, and thus the BARK/beta-arrestin system is believed to play a major role in regulating receptor-mediated immune functions.

Application Notes

The stated application concentrations are suggested starting amounts. Titration of the beta Arrestin 1 antibody may be required due to differences in protocols and secondary/substrate sensitivity.


An amino acid sequence from the N-terminus of human ARRB1 (ANVQSFPPAPEDKKPLTRLQER) was used as the immunogen for this beta Arrestin 1 antibody (100% homologous in human, mouse and rat).


After reconstitution, the beta Arrestin 1 antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
