酸感应离子信道2 (ASIC2)也称为 氢离子敏感阳离子频道1、神经元 (ACCN1)或 大脑钠通道1 (BNaC1)是一个蛋白质，在人类中的编码的ASIC2 基因. ASIC2基因是五个旁系同源基因编码蛋白质，形成三聚酸感应离子频道 (Asic)在哺乳动物。^[6] CDNA的这种基因第一个克隆在1996年。^[7]^[8]^[9]^[10] ASIC基因可以通过不同的拼接形成不同类型的蛋白质变体。

这些基因主要是在中央和周围神经系统。

可以形成异三聚体渠道。^[11]^[12]

结构和功能

这个基因编码的成员ASIC家族的蛋白质。^[13] 其中有许多氨基酸残留与保守的间隔。 TM的区域一般都是象征作为TM1(克隆N端)和TM2(靠近C端).

孔道通过离子选择性地流动，从外面到细胞质形成由三TM2地区的三聚体。^[6]
