Threonine347 (T347) is a major phosphorylation site of the CXCR2 receptor. The pT347-CXCR2 antibody detects phosphorylation in response to high- and low-efficacy agonists but not after PKC activation. T347 phosphorylation is a key regulator of CXCR2 desensitization, β-arrestin recruitment and internalization.

Figure 1. Agonist-induced Threonine347 phosphorylation of the CXC Chemokine Receptor 2. Upper panel, HEK293 cells stably expressing the CXC Chemokine Receptor 2 (CXCR2) were either not exposed or exposed to 100 nM specific CXC Chemokine receptor 2 agonist CXCL6 for 30 minutes. Cells were lysed and immunoblotted with the anti-pT347-CXCR2 antibody (7TM0069A) at a dilution of 1:1000. Lower panel, blot was stripped and reprobed with an phosphorylation-independent anti-CXCR2 antibody to confirm equal loading of the gel.
