WebWe attribute this anomalous inward-rectifying current to the formation of a gating pore in the mutant channel, as supported by dramatically increased current amplitude in the presence of extracellular guanidinium , as previously reported for gating pore currents in R/X mutations of S4 in Nav1.4 (Sokolov et al., 2010).
