Figure 2 Analysis of PI(4,5)P2 regulation regarding the two steps of TMEM16A activation. (A) Representative Cl? current traces activated by a voltage step to +50 mV before (control) and after Dr-VSP activation in cells expressing TMEM16A(ac) in the presence of a 115 nM intracellular Ca2+ concentration. Black trace: control (before Dr-VSP activation). Red trace: after Dr-VSP activation. The dotted line indicates zero current. The horizontal dashed lines (blue) indicate the separation point for the instantaneous and slow currents. IInst?instantaneous Cl? current; ISlow?slow Cl? current. (B) Inhibition (%) of the instantaneous (top) and slow (bottom) currents in response to PI(4,5)P2 depletion by Dr-VSP activation in cells expressing TMEM16A(a) or TMEM16A(ac); n = 5?7. Dots indicate the individual data points for each cell. Bars indicate means ± SEM. ** p < 0.01, *** p < 0.001, one-way ANOVA followed by Sidak?s post hoc test.
