Description: Rabbit IgG polyclonal antibody for Beta-arrestin-1(ARRB1) detection. Tested with WB, IHC-P in Human, Mouse, Rat.
Background: Arrestin, beta 1, also known as ARRB1, 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. Arrestin beta 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.

NCBI Description

Members of arrestin/beta-arrestin protein family are thought 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. Arrestin beta 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. Alternatively spliced transcripts encoding different isoforms of arrestin beta 1 have been described. [provided by RefSeq, Jan 2011]

Uniprot Description

ARRB1: regulates G-protein coupled receptors (GPCR) signaling by mediating both receptor desensitization and resensitization processes. Binds to GRK-phosphorylated receptor and sterically preclude its coupling to the cognate G- protein; the binding appears to require receptor determinants exposed only in the active receptor conformation. Targets many receptors for internalization by acting as endocytic adapters (CLASPs, clathrin-associated sorting proteins). Internalized arrestin-receptor complexes traffic to intracellular endosomes, where they remain uncoupled from G-proteins. Two different modes of arrestin-mediated internalization occur. Beta-arrestins function as multivalent adapter proteins that can switch the GPCR from a G-protein signaling mode that transmits short-lived signals from the plasma membrane via small molecule second messengers and ion channels to a beta-arrestin signaling mode that transmits a distinct set of signals that are initiated as the receptor internalizes and transits the intracellular compartment. Also involved in regulation of receptors other than GPCRs. Involved in Toll-like receptor and IL-1 receptor signaling through the interaction with TRAF6 which prevents TRAF6 autoubiquitination and oligomerization required for activation of NF-kappa-B and JUN. Binds phosphoinositides. Binds inositolhexakisphosphate (InsP6). Involved in IL8-mediated granule release in neutrophils. Interacts with phosphorylated ADRB2 and CHRM2. Interacts with SRC (via the SH3 domain and the protein kinase domain); the interaction is independent of the phosphorylation state of SRC C-terminus. Interacts with RAF1, CHUK, IKBKB and Nik. Interacts with DVL1 and DVL2; the interaction is enhanced by DVL phosphorylation. Interacts with IGF1R. Belongs to the arrestin family. 2 isoforms of the human protein are produced by alternative splicing.
