Figure 1. KvLQT1 channel current recorded in Xenopus oocytes.

Figure 1

A, KvLQT1 channel current recorded during 2 s pulses from -70 to +40 mV. Deactivating tail currents were elicited by repolarization to −70 mV. B, normalized steady-state I-V relationship for KvLQT1 channel current. Current at the end of a 2 s pulse was normalized to current at +60 mV (n = 18). C, time constants for activation of KvLQT1 channel current, determined from two-exponential fits to the activating phase (n = 17). D, relative amplitude of the fast component of KvLQT1 channel activation (n = 17). Ampf and Amps are the amplitudes of the fast and slow components of activation, respectively.
