• Product NameArrestin 1 (Phospho-Ser412) Antibody
• Host SpeciesRabbit
• ClonalityPolyclonal
• PurificationAntibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. Non-phospho specific antibodies were removed by chromatogramphy using non-phosphopeptide.
• ApplicationsWB IHC
• Species ReactivityHu
• SpecificityThe antibody detects endogenous levels of Arrestin-1 only when phosphorylated at serine 412.
• Immunogen TypePeptide-KLH
• Immunogen DescriptionPeptide sequence around phosphorylation site of Serine 412 (T-G-S(p)-P-Q) derived from Human Arrestin 1.

Functions in regulating agonist-mediated G-protein coupled receptor (GPCR) signaling by mediating both receptor desensitization and resensitization processes. During homologous desensitization, beta-arrestins bind to the GPRK-phosphorylated receptor and sterically preclude its coupling to the cognate G-protein; the binding appears to require additional receptor determinants exposed only in the active receptor conformation.
