Threonine362/Serine363 (T362/S363) is a major phosphorylation site of the Neuropeptide Y Receptor 1. The pT362/pS363-NPY1 antibody detects phosphorylation in response to high- and low-efficacy agonists but not after PKC activation. T362/S363 phosphorylation is primarily mediated by GRKs and is a key regulator of NPY1 desensitization, β-arrestin recruitment and internalization.

Figure 1. Agonist-induced Threonine362/Serine363 phosphorylation of the Neuropeptide Y receptor 1. Upper panel, HEK293 cells stably expressing the NPY1-Receptor (NPY1) were either not exposed or exposed to 1 µM of NPY1 receptor agonist Neuropeptide Y for 30 minutes. Cells were lysed and immunoblotted with the anti-pT362/pS363-NPY1 antibody (7TM0305B) at a dilution of 1:1000. Lower panel, blot was stripped and reprobed with an phosphorylation-independent anti-NPY1 antibody to confirm equal loading of the gel.
