【答案】： 这类通道的构型变化依据细胞内外带电离子的状态，主要是通过膜电位的变化使其构型发生改变，从而将“门”打开。在很多情况下，门通道有其自己的关闭机制，它能快速地自发关闭。开放往往只有几毫秒时间。在这短暂瞬息时间里，一些离子、代谢物或其它溶质顺着浓度梯度自由扩散通过细胞膜。电位-门...
4.6. How do voltage-gated ion channels function in epithelia? What remains an important piece of the puzzle is whether voltage-gated ion channels such as CaV1 exhibit the same conductance properties and kinetics in epithelia as they do in excitable tissues like neurons and muscles. If the major...
voltage-gated ion channelcell membraneThis chapter discusses the molecular architecture of the cell membrane of mammalian axons. It focuses on the distribution and development of voltage-gated ion channels, their roles in axonal function, and their relevance to neurological disorders....
Voltage-gated sodium (Nav) channels function as the main drivers of the depolarization phase of action potentials. As such, they are ubiquitously found in a wide range of excitable tissues, playing fundamental roles in many vital physiological functions, such as skeletal muscle contraction, heart be...
