摘要
氯通道是细胞膜上一类离子选择性跨膜蛋白,其功能是调节细胞内部溶液pH、细胞容积、盐类离子转运以及细胞电兴奋性。按照离子输运方式的差异,氯通道膜蛋白可分为氯离子通道和Cl^(-)/H^(+)转运体两类,其中Cl^(-)/H^(+)转运体内部的离子转运过程具有显著耦合性,且该过程需要借助水分子参与。本文针对Cl^(-)/H^(+)耦合转运微观机制研究进行总结及展望,为氯通道实验研究、临床疾病诊治和新药研发提供理论依据。
Chloride channels are one kind of ion selective transmembrane proteins.Their functions are regulating intracellular solution pH,cell volume,salt ion transport and cell excitability.According to difference of ion transport modes,chloride channel membrane proteins can be divided into chloride ion channel and Cl^(-)/H^(+)transporter.Among them,ionic transport process in Cl^(-)/H^(+)transporter shows significant coupling,and needs the participation of water molecules.In this paper,we summarize and prospect the microscopic coupling transport mechanism of Cl^(-)/H^(+),which can provide theoretical basis for experimental research of chloride channels,clinical disease diagnosis and treatment and new drug development.
