ARRB2 arrestin beta 2 [ Homo sapiens (human) ]
Source: NCBI Gene (ID 409)
Symbol: ARRB2
Full name: arrestin beta 2
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Also known as: ARB2; ARR2; BARR2
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 2, like arrestin beta 1, was shown to inhibit beta-adrenergic receptor function in vitro. It is expressed at high levels in the central nervous system and may play a role in the regulation of synaptic receptors. Besides the brain, a cDNA for arrestin beta 2 was isolated from thyroid gland, and thus it may also be involved in hormone-specific desensitization of TSH receptors. Multiple alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2012]
