Thus a receptor may be a protein, enzyme, membrane channel, or a region of a foreign pathogen.

这样的受体可以是蛋白质、酶、膜通道或外来病原体的一个区域。

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。

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。

So, what happens, this is another view of a sodium channel, so this is actually looking a little bit more at the protein structure.

那么，这里发生了什么，这是钠离子通道的另一张图片，在这种蛋白质结构中,它看起来更复杂一点。

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.
