FIGURE 3.
Activation and inactivation of the I470Y channel. (A) Currents associated with voltage steps from −120 to +60 mV in 10-mV increments, followed by a step to +40 mV. (B) Steady-state inactivation curve based on the recordings in A. (C) Peak-conductance curves for I470Y and ShIR, measured as Gpeak1 = Ipeak1/(V − EK). Each point is the mean value from six or seven experiments.
