Background

Members of arrestin/beta-arrestin protein family are thought to participate in agonist-mediated desensitization ofG-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 thebeta-adrenergic receptor kinase (BARK) mediated desensitization of beta-adrenergic receptors. Besides the centralnervous system, it is expressed at high levels in peripheral blood leukocytes, and thus the BARK/beta-arrestin systemis believed to play a major role in regulating receptor-mediated immune functions. Alternatively spliced transcriptsencoding different isoforms of arrestin beta 1 have been described, however, their exact functions are not known.(provided by RefSeq)
