The antibody detects endogenous levels of Arrestin-1 only when phosphorylated at serine 412.
Purification
Antibodies were purified by affinity-chromatography using epitope-specific peptide.
Immunogen
Arrestin 1 (phospho Ser412) antibody was raised against a peptide sequence around phosphorylation site of Serine 412 (T-G-S (p)-P-Q) derived from Human Arrestin 1.

Background
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.
