Threonine359/Serine360 (T359/S360) is major phosphorylation site of the Bombesin Receptor 2 (BB2). The pT359/pS360-BB2 antibody detects phosphorylation in response to agonists. T359/S360 phosphorylation is likely to be involved in efficient ligand sequestration by BB2.

Figure 1. Agonist-induced Threonine359/Serine360 phosphorylation of the Bombesin Receptor 2. Upper panel, HEK293 cells stably expressing the Bombesin receptor 2 (BB2) were either not exposed or exposed to 100 nM Bombesin for 30 minutes. Cells were lysed and immunoblotted with the anti-pT359/pS360-BB2 antibody (7TM0039A) at a dilution of 1:1000. Lower panel, blot was stripped and reprobed with the phosphorylation-independent anti-BB2 antibody (7TM0039N) to confirm equal loading of the gel.
Figure 2. Analysis of dose-dependent Bombesin Receptor 2 phosphorylation using two phosphosite-specific antibodies. Upper two panels, HEK293 cells stably expressing the Bombesin Receptor 2 (BB2) were either not exposed or exposed to increasing concentrations of Bombesin ranging from 1 nM to 10 μM for 30 minutes. Cells were lysed and immunoblotted with the anti-pT359/pS360-BB2 antibody (7TM0039A) or anti-pS363/pS364-BB2 antibody (7TM0039B) at a dilution of 1:1000. Lower panel, blot was stripped and reprobed with the phosphorylation-independent anti-BB2 antibody (7TM0039N) at a dilution of 1:1000 to confirm equal loading of the gel.
