Functional properties of the homomericKCNQ2 variants. (A) Macroscopic current traces recorded in CHO cells transfected with KCNQ2 variants (3μg) in homomeric configuration. Current scale, 250 pA; time scale, 200 ms. (B) Mean current densities of KCNQ2 channel at +40 mV in the homozygous state. (C) Current–voltage relationships of the KCNQ2 homomeric channel were determined from tail current amplitudes. Lines represent fits of a Boltzmann function. (D) Differences in activation of V0.5 were determined for the KCNQ2 channel expressed in the homozygous state (n = 8–15). Statistically significant differences *p < 0.05 versus WT KCNQ2.
