Figure 3. KCNE1-D76N and KCNE1-Δ70 shift the voltage dependence of activation of IKs.

Figure 3

A) voltage-dependent activation curves, and B) normalized activation curves. Curves were fitted using a Boltzmann function. Vh for KCNQ1 = −30.3±1.0 mV, KCNQ1/KCNE1 = 9.5±4.2 mV, KCNQ1/KCNE1-D76N = 43.5±3.0 mV, KCNQ1/KCNE1-Δ70 = 71.5±7.0 mV. n = 6, p<0.001 for both mutants compared to wild-type KCNE1.
