The mutation itself is in a gene for a nerve-cell protein of a type known as an ion channel.

变异的基因是编码一种叫做离子通道的神经细胞蛋白质。

An ion channel is a protein that lets charged particles enter or leave a cell to generate electrical signals, a basic process of nerve cell communication.

离子通道是可以让带电粒子进入或离开细胞，产生电信号的一类蛋白，是神经细胞交流的基础。

Most attention has focused on the M2 protein, an ion channel that protrudes from the virus's surface and tells it when it is inside a cell.

M2蛋白获得重点关注。离子通道M2蛋白突出于病毒表面，当病毒进入细胞内后通知病毒。

The one that's on the top here is called ligand-gated ion channel and an ion channel is a protein that sits in the surface of a cell.

最上面的这个叫作配体门控离子通道,离子通道是一类位于细胞表面的蛋白

It can also happen in other ways, it could be a G-protein coupled receptor which we talked about last time, which indirectly activates another ion channel to start the electrical signal.

还可以有其他方式,可以通过G蛋白偶联受体,这我们上次谈过,它可以间接激活,另一个离子通道以开启电信号

With the help of Chiara Cirelli, who also works at the University of Wisconsin, Dr Tononi has created a mutant fruit fly that sleeps only two or three hours a night. (A normal fly sleeps between eight and 14 hours.) The mutation itself is in a gene for a nerve-cell protein of a type known as an ion channel.
