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

西尼罗河病毒质双分子层上的包膜蛋白（E）通过网格蛋白介导的内吞作进入宿主细胞。

Our research aims to reveal the atomic structures of membrane proteins that take sugars, calcium ions, and sodium ions into our cells.

我们的研究旨在揭示将糖、离子和钠离子带入我们细胞的膜蛋白的原子结构。

Some proteins can't be crystallized like membrane proteins.

有些蛋白质不能像膜蛋白那样结晶。

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.

它是离子通道变的结果。离子特异性通道是通道的一个子类，属于与通道红细胞蛋白不同的跨膜蛋白组。

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

跨膜蛋白贯穿双层结构，形成通道，使特定分子如钠离子和钾离子得以通过。

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

事实上，我们所知的一些最毒的物质，正是由感染性细菌制造的穿膜蛋白。
