- Extra Details:
- b-arrestin 1 (ARRB1, ARB1, ARR1) is a member of the arrestin protein family, which also includes visual arrestin, cone arrestin and b-arrestin 2. b-arrestins bind phosphorylated heptahelical G protein coupled receptors to desensitize and target them to clathrin-coated pits for endocytosis. b-arrestin 1 acts as a cofactor in the b-adrenergic receptor kinase (BARK)-mediated desensitization of b-adrenergic receptors, resulting in specific dampening of cellular responses to stimuli such as hormones, neurotransmitters or sensory signals (1). b-arrestin 1 exists as two alternately spliced transcripts, encoding two isoforms. Isoform A is a longer variant, while isoform B lacks an alternate in-frame exon compared to isoform A, resulting in a shorter protein (1). The functions of the isoforms have not been fully described. b-arrestin 1 is a cytosolic protein, and is widely expressed in cells, particularly in the central nervous system and in peripheral blood leukocytes (2). Applications: Suitable for use in Immunofluorescence/Immunocytochemistry, ELISA and Western Blot. Other applications not tested. Recommended Dilutions: Immunofluorescence (IC): 2ug/ml Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
