This is a Arrestin 1 (Phospho-Ser412) Phospho-Specific Antibody from Reddot Biotech. This product is for Research Use Only.
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.
