The outward rectifier K+ current current was the dominant K+ current in the whole cell currents in Deiters' cells. In the presence of 200μ M linopirdine, the Ik current was not significantly effected. Our findings demonstrated that the KCNQ heteromeric or homomeric potassium channel may be the molecular basis for the peak outward K+ current and testified that the inward IKn current is mediated by KCNQ potassium channel.
