摘要
Abstract Voltage‐gated potassium channels are oligomeric membrane proteins that form ion pores highly selective for K + ions. Upon depolarization of the cell membrane, these channel proteins undergo molecular rearrangements leading to rapid activation, i.e. opening of the channels and, in some cases, subsequent inactivation.
