离子通道型受体

酪氨酸激酶型受体、G蛋白偶联受体和离子通道型受体是细胞表面三类主要受体。

Receptor tyrosine kinases ( RTK ), G protein-coupled receptors ( GPCR ) and ion channel receptors are main cell surface receptors .

P2受体可再分为两类，即配体门控离子通道型受体（P2X受体）和G蛋白偶联型受体（P2Y受体）。分子生物学研究结果显示：P2X受体包括七种亚型，即P2X1～7；

The P2 receptors are divided into two categories : the ligand-gated ion channel receptors ( P2X ) and the G protein-coupled receptors ( P2Y ) .

离子通道型谷氨酸受体包括AMPA/KA和NMDA受体两大类。

Two classes of ion-channel type glutamate receptors involve in NMDA receptors and AMPA / KA receptors .

NMDA受体（N-methyl-D-aspartatereceptors，NMDA受体）是哺乳动物神经系统中重要的离子通道型谷氨酸受体。

N-methyl-D-aspartate receptors ( NMDA receptors , NMDARs ), as the ion channel-type glutamate receptors , are vital for mammal neuron system .

在拟南芥中发现了有20个谷氨酸受体基因（AtGLRs）的家族，其编码的氨基酸序列和动物的离子通道型谷氨酸受体（iGluRs）有很高同源性，并可分为3个亚族。

Currently , 20 Arabidopsis glutamate receptor genes ( AtGLRs ) were discovered and divided into three subfamilies , whose amino acid coding sequences had high similarity with animal inotropic glrtamate ( iGLRs ) receptors .
