Product Specific Information

PEP-156 is a 14 amino acid synthetic peptide whose sequence is derived from human beta-arrestin2 protein. The sequence of this peptide is (amino to carboxy terminus): C-D (384)-D-I-V-F-E-D-F-A-R-L-R-L-K (397)

This peptide may be used for neutralization and control experiments with the polyclonal antibody that reacts with this product and human beta-arrestin2, catalog # PA1-730. Using a solution of peptide of equal volume and concentration to the corresponding antibody will yield a large molar excess of peptide (~70-fold) for competitive inhibition of antibody-protein binding reactions.

Reconstitute with 0.1 mL of distilled water.

Target Information

Beta-arrestin-2, or ARRB2, is an adaptor protein belonging to the arrestin family with an N- arrestin domain and a C- arrestin domain. ARRB2 is a regulatory protein involved in heterotrimeric G protein-coupled receptor desensitization and is known to regulate beta2-adrenergic receptor (beta2AR) function by enhancing beta2AR mediated nuclear translocation of ERK. ARRB2 binds to phosphorylated beta2ARs, thereby causing a significant impairment of their capacity to activate G(S) proteins. Along with AIP4, ARRB2 acts as an endosomal sorting molecule that mediates CXCR4 entry into a degradative pathway. It may also be involved in hormone-specific desensitization of TSH receptors. ARRB2 is a Ca2+ binding protein of the retinal outer segments and binds to P-rhodopsin and is also involved in synaptic transmission in photoreceptor cells. It is widely expressed in most of the tissues, especially neuronal tissues and spleen.
