Characterization of currents in I470Y. (A) Comparison between the activation rates of I470Y and ShIR at approximately equal open probabilities (0.5). (B) Same as in A but at a faster time scale. (C) The quotient between current at 2.5 s and peak current-versus-voltage curve, showing the U-type resembling voltage dependence of the inverted inactivation component. Each point is the mean value from six or seven experiments.
