Figure 4. — Extracellular acidification does not inhibit Na⁺ current through the inactivation-deficient mutant hKv1.5-R487V. (A and B) Na⁺ currents from the same cell in response to the step voltage protocol shown above the current traces at pH 7.4 and pH 6.4. (C and D) Superimposed tail currents during the envelope of voltage steps shown above the current traces at pH 7.4. The depolarization to 40 mV was initially 1 ms in duration and the protocol was repeated every 10 s for increasing durations up to 500 ms.
