Anti-S1P1

Sphingosine-1-phosphate (S1P) exerts its activity by binding to five distinct G-protein-coupled receptors, S1P1/EDG-1, S1P2/EDG-5, S1P3/EDG-3, S1P4/EDG-6, and S1P5/EDG-8. S1P1 primarily couples with pertussis toxin-sensitive Gi/o proteins to mediate S1P-induced cell proliferation, survival, migration, cytoskeletal organization, and morphogenesis. Expression of S1P1 is abundant in embryological vasculature and is ubiquitously expressed in adult cells suggesting diverse physiological functions of this receptor. The human and mouse S1P1 receptors have 382 amino acids with an estimated molecular weight of 43 kDa. Glycosylation at the N-terminal extracellular domain may cause the protein to migrate at a higher position in SDS-PAGE. Cayman's S1P1 Polyclonal Antibody detects the receptor at 47 kDa by WB analysis. The antibody can also be used for IF and IHC to study expression patterns of this protein.Synonyms: EDG-1, S1PR1, Sphingosine-1-phosphate Receptor 1.
