Serine364 (S364) is a major phosphorylation site of the β2 adrenoceptor. The pS364-β2 antibody detects phosphorylation in response to high- and low-efficacy agonists but not after PKC activation. S364 phosphorylation is primarily mediated by GRK2 and is a key regulator of β2 desensitization, β-arrestin recruitment and internalization.

Figure 1. Agonist-induced Serine364 phosphorylation of the β2-Adrenoceptor. Upper panel, HEK293 cells stably expressing the β2-Adrenoceptor (β2) were either not exposed or exposed to 1 µM of specific β2-adrenoceptor agonist Isoprenaline for 30 minutes. Cells were lysed and immunoblotted with the anti-pS364-β2 antibody (7TM0029F) at a dilution of 1:1000. Lower panel, blot was stripped and reprobed with the phosphorylation-independent anti-β2 antibody (7TM0029N) at a dilution of 1:1000 to confirm equal loading of the gel.
