Figure 4.
Voltage dependence of TMEM16B. (A) Normalized conductances at the indicated [Ca2+]i calculated from tail currents at −100 mV after prepulses between −200 and +200 mV were plotted versus the prepulse voltage (n = 4–9). Lines are the fit to the Boltzmann equation (Eq. 2). (B) V1/2 and z (inset) values plotted versus [Ca2+]i.
