You could watch where it localizes in the cell, there are fluorescent assays you could use to determine what other proteins it interacts with.

你可以看到它在细胞的什么地方，你可以用荧光化验的办法确定,它和其它什么蛋白质相作用。

The other beauty about - beautiful thing about proteins is that if you make subtle conformational changes, often those changes are reversible.

蛋白质的另一个美妙之处就是,如果蛋白质发生一些小的构像改变,这些改变通常是可逆的

These junctions, these red dots here are actually made up of proteins, some are synthesized by one cell, some are synthesized by each other, and they lock together to form a very tight barrier, to form a tight junction between the two cells.

这些红点表示细胞连接,实际上是由蛋白质构成的,有些是由一个细胞单独生成的,有些是由两个细胞共同生成,使这两个细胞紧锁在一起形成紧密的屏障,并在两细胞间形成紧密连接

The other thing that it does is that when a virus is inside these cells making its proteins, some of those proteins get processed or digested into small fragments that are themselves antigens.

HC的另一项作用是,当病毒在细胞内表达蛋白时,一些蛋白被加工,或者,分解成小片段而成为抗原

It breaks down into its component parts and I show two of those component parts here, one is the genetic material, in this case DNA, and the other is all the proteins that form the structure of the virus.

分解为自身各种零件,这里给你们展示一下其中的两个,其一是遗传物质,这里指DNA,另一个是构建病毒结构的所有蛋白质
