Product Data

• Species: Human
• Expression Host: E. coli
• Expression cDNA Clone or AA Sequence:
  Protein Sequence

  Met1-Arg418
• Tag: C-His
• Predicted MW: 48.1 kDa
• Concentration: lot specific
• Purity: >95% as determined by SDS-PAGE and Coomassie blue staining
• Buffer: Lyophilized from a 0.2 um filtered solution of PBS, pH 7.4.
• Endotoxin: < 0.1 EU per µg protein as determined by LAL test
• Reconstitution Method: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. Dissolve the lyophilized protein in ddH2O. It is not recommended to reconstitute a concentration less than 100 µg/ml. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
• Storage: Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
• Stability: Stable for at least 6 months from date of receipt under proper storage and handling conditions.
• Shipping: Ambient

• 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. [provided by RefSeq, Jan 2011]
