Effect of charge neutralization in IIS4 and IIIS4 on steady-state inactivation and activation. Steady-state inactivation (left panels) and activation (right panels) curves of WT, IIS4, IIIS4, and IVS4 mutants. Representative barium currents through WT and mutant channels during a 3000-ms depolarization from −80 mV to the peak potential (PP) of the I–V curves are shown in corresponding insets. WT (PP 10 mV); IIS4(R2Q/R3Q/R4Q/K5Q/R6Q) (PP 10 mV); IIIS4(K1Q/R2Q/R3Q/R4Q) (PP 10 mV); IVS4(R2Q) (PP 20 mV)
