Serine385 (S385) is a major phosphorylation site of the Orexin receptor 1 (OX1). The pS385-OX1 antibody detects phosphorylation in response to high-efficacy agonists. S385 phosphorylation is a key regulator of OX1 desensitization, β-arrestin recruitment and internalization.

Figure 1. Agonist-induced Serine385 phosphorylation of Orexin Receptor 1. Upper panel, HEK293 cells stably expressing the Orexin Receptor 1 (OX1) were either not exposed or exposed to 100 nM Orexin-B for 30 minutes. Cells were lysed and immunoblotted with the anti-pS385-OX1 antibody (7TM0321A) at a dilution of 1:1000. Lower panel, blot was stripped and reprobed with an phosphorylation-independent anti-OX1 antibody to confirm equal loading of the gel.
