Serine353/Serine355 (S353/S355) is major phosphorylation site of the Sphingosine 1-Phosphate Receptor 1 (S1P1). The pS353/pS355-S1P1 antibody detects phosphorylation in response to agonists. S353/S355 phosphorylation is likely to be involved in efficient ligand sequestration by S1P1.

Figure 1. Agonist-induced Serine353/Serine355 phosphorylation of the Sphingosine 1-Phosphate Receptor 1. Upper panel, HEK293 cells stably expressing the S1P1-Receptor (S1P1) were either not exposed or exposed to 1 µM of S1P1-Receptor agonists S1P for 30 minutes. Cells were lysed and immunoblotted with the anti-pS353/pS355-S1P1 antibody (7TM00275B) at a dilution of 1:1000. Lower panel, blot was stripped and reprobed with an phosphorylation-independent anti-S1P1 antibody to confirm equal loading of the gel.
