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。离子特异性通道是钙通道的一个子类，属于与通道红细胞蛋白不同的跨膜蛋白组。
