Serine320/Serine321 (S320/S321) is a major phosphorylation site of the CXCR6 receptor. The pS320/pS321-CXCR6 antibody detects phosphorylation in response to high- and low-efficacy agonists but not after PKC activation. S320/S321 phosphorylation is a key regulator of CXCR6 desensitization, β-arrestin recruitment and internalization.

Figure 1. Agonist-induced Serine320/Serine321 phosphorylation of the CXC Chemokine Receptor 6. Upper panel, HEK293 cells stably expressing the CXC Chemokine Receptor 6 (CXCR6) were either not exposed or exposed to 100 nM specific CXC Chemokine receptor agonist CXCL16 or 0.1 μM PMA (Phorbol 12-Myristate 13-Acetate) for 30 minutes. Cells were lysed and immunoblotted with the anti-pS320/pS321-CXCR6 antibody (7TM0073A) at a dilution of 1:1000. Lower panel, blot was stripped and reprobed with an phosphorylation-independent anti-CXCR6 antibody to confirm equal loading of the gel.
Figure 2. Analysis of dose-dependent CXC Chemokine Receptor 6 phosphorylation using three phosphosite-specific antibodies. Upper two panels, HEK293 cells stably expressing the CXC Chemokine Receptor 6 (CXCR6) were either not exposed or exposed to increasing concentrations of CXCL16 ranging from 3 nM to 100 nM for 30 minutes. Cells were lysed and immunoblotted with the anti-pS320/pS321-CXCR6 antibody (7TM0073A) or anti-pS325/pT327-CXCR6 antibody (7TM0073B) or anti-pS329/pS331-CXCR6 antibody (7TM0073C) at a dilution of 1:1000. Lower panel, blot was stripped and reprobed with an phosphorylation-independent anti-CXCR6 antibody to confirm equal loading of the gel.
