Mechanisms of sodium channel inactivation.

Abstract excerpt

Rapid inactivation of sodium channels is crucial for the normal electrical activity of excitable cells. There are many different types of inactivation, including fast, slow and ultra-slow, and each of these can be modulated by cellular factors or accessory subunits. Fast inactivation occurs by a 'hinged lid' mechanism in which an inactivating particle occludes the pore, whereas slow inactivation is most likely to...
