Figures аnd infоrmаtiоn belоw is for questions 25-29. Experimentаl description and data: Bradykinin is a small 9 amino acid peptide that binds and activates a GPCR that couples to the Gq class of heterotrimeric G proteins. In Figure 1A, cultured epithelial cells were stimulated with 10 nM bradykinin for increasing periods of time. Cellular lysates were prepared for each time point and protein samples separated by gel electrophoresis. Phosphorylation of ERK (a MAPK) was measured by immunoblotting with an anti-phospho-ERK antibody (top blot). The same blot was ‘stripped’ of the anti-phospho-ERK antibody, and re-probed with an antibody for ERK independent of its phosphorylation state, i.e. ‘Total ERK’ (bottom blot). The time course plot (lower panel A) represents the intensities of phospho-ERK bands relative to total-ERK, expressed as percentages of the control (no BK treatment). Why does 20 minutes of BK stimulation cause lower ERK phosphorylation than 5 minutes of BK stimulation? What mechanisms might account for this? (2 points)
