【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...
Voltage-Gated K+ ChannelsK+ selective channels are some of the most widespread ion trafficking molecules in living organisms, with more than 70 genes encoding different K+ channels in humans. KV channels fall into one of the two classical categories of delayed rectifier (DR) and A-type. ...

Voltage-Gated Ion Channels 来自 钛学术 喜欢 0 阅读量: 61 作者: F Bezanilla 摘要: The bit of information in nerves is the action potential, a fast electrical transient in the transmembrane voltage that propagates along the nerve fiber. In the resting state, the membrane potential of the ...
Voltage-gated sodium, calcium, and potassium channels generate electrical signals required for action potential generation and conduction and are the molecular targets for a broad range of potent neurotoxins. These channels are built on a common structur
Ca 2+ channels in many different cell types activate upon membrane depolarization, and mediate Ca 2+ influx in response to action potentials and sub-threshold depolarizing signals. Signal transduction in different cell types involves different molecular subtypes of voltage-gated Ca 2+ channels, which...
