Now, west nile virus enters host cells using a lipid membrane protein called E2 in a process called clathrin-mediated endocytosis.

西尼罗河病利用脂质双分子层上的包膜蛋白（E）通过网格蛋白介导的内吞作用进入宿主。

In fact, some of the most toxic substances we know of are membrane-breaching proteins made by infectious bacteria.

事实上，我所知道的一些强的物质是由传染菌产生的破膜蛋白。

Transmembrane proteins stretch across the bilayer to create channels that allow specific molecules through, like sodium and potassium ions.

跨膜蛋白伸展穿过双层以创建允许特定分子通过的通道，例如钠离子和钾离子。

It is the consequence of a mutation in a calcium ion channel gene Ion specific channels of which calcium channels are a subclass belong to a different group of transmembrane proteins from the channel redopsins.

它是钙离子通道基因突变的结果。离子特异通道是钙通道的一个子类，属于与通道红蛋白不同的跨膜蛋白组。
