Background Information The Arrestin family consists of four members: Arrestin 1 (visual Arrestin), Arrestin 2 (beta Arrestin 1), Arrestin 3 (beta Arrestin 2), and Arrestin 4 (cone Arrestin). While visual and cone Arrestins are found almost exclusively in the retina, beta Arrestins 1 and 2 are ubiquitously expressed. Beta Arrestins appear to act as negative regulators on G protein-coupled receptors, (Lefkowitz, 1998). Interaction with molecules such as clathrin, AP-2 and NSF directs the clathrin-mediated internalization of G-protein-coupled receptors. Interaction with molecules such as Src, Raf, Erk, ASK1 and JNK3 appears to regulate several pathways that result in the activation of MAP kinases, (Lin, 1998; Miller, 2001).

Entrez Gene Number
Entrez Gene Summary 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, however, their exact functions are not known. [provided by RefSeq]
Gene Symbol
  • ARRESTIN
  • S-AG
  • S-arrestin
Purification Method Ammonium Sulfate Precipitation
UniProt Number
UniProt Summary FUNCTION: Regulates beta-adrenergic receptor function. Beta-arrestins seem to bind phosphorylated beta-adrenergic receptors, thereby causing a significant impairment of their capacity to activate G(S) proteins.
SEQUENCE SIMILARITIES: Belongs to the arrestin family.
