Glutamate binds to NMDA receptors which tell the cell to open up calcium ions channels.

谷氨酸与NMDA受体结合，使细胞钙离子通道打开。

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。
