Voltage and time dependence of recovery from inverted inactivation in I470Y. (A) Lack of recovery in currents associated with voltage steps from −80 mV to −40 mV, repeated at a frequency of 0.2 Hz. (B) Lack of recovery from inactivation induced at −40 mV after pulse steps down to −170 mV. Superimposed currents. (C) Voltage dependence of recovery from the inactivation induced at −40 mV, measured as Ipeak2/max Ipeak2. (D) Recovery from the inactivation induced at −40 mV after a 2.5-ms duration pulse step to +40 mV (Δt = 2.5 ms). (E) The dependence of the recovery from inactivation on the duration (Δt = 2.5–50 ms) of a pulse step to +40 mV, measured as Ipeak4/Ipeak1 (see D). Half-time value is 1.9 ms.
