Serine335/Serine337 (S335/S337) is major phosphorylation site of the Sphingosine 1-Phosphate Receptor 3 (S1P3). The pS335/pS337-S1P3 antibody detects phosphorylation in response to agonists. S335/S337 phosphorylation is likely to be involved in efficient ligand sequestration by S1P3.

Figure 1. Agonist-induced Serine335/Serine337 phosphorylation of the Sphingosine 1-Phosphate Receptor 3. Upper panel, HEK293 cells stably expressing the S1P3-Receptor (S1P3) were either not exposed or exposed to 1 µM of S1P3-Receptor agonists S1P for 30 minutes. Cells were lysed and immunoblotted with the anti-pS335/pS337-S1P3 antibody (7TM00277A) at a dilution of 1:1000. Lower panel, blot was stripped and reprobed with the phosphorylation-independent anti-S1P3 antibody (7TM00277N) at a dilution of 1:1000 to confirm equal loading of the gel..
