Electrophysiological properties of zShal3 expressed in Xenopus oocytes. A and B: Representative traces of zShal3 (A) and Kv4.3 currents (B). Currents were elicited by 1000 ms voltage steps from a holding potential of -120 mV to test potentials between -100 and +50 mV in 10 mV increments at every 15 s.C: Voltage dependence of activation and inactivation of zShal3 currents. The conductance-voltage curves were constructed by dividing the current by the driving force and normalizing to the maximal conductance (G_max) at +120 mV for activation and at -150 mV for inactivation curve.D: Recovery from inactivation of zShal3 currents at -120 mV.
