水通道蛋白，又称水蛋白（ａｑｕａｐｏｒｉｎ，ＡＱＰ），是一系列具有同源性的内在膜蛋白家族成员。迄今，已从哺乳动物组织中鉴定出８种水蛋白，它们广泛分布于机体不同的组织器官中，介导着不同类型细胞膜的跨膜水转运，其功能受到某些因素的影响，并与某些疾病的发生有着密切的关系。水通道的研究有助于更深入地了解某些病理生理机制，为某些疾病的治疗提供新的途径。 Aquaporin, also known as aquaporin (AQP), is a member of a family of homologous inner membrane proteins. So far, eight kinds of water proteins have been identified from mammalian tissues. They are widely distributed in different tissues and organs of the body, and mediate transmembrane water transport of different types of cell membranes. Their functions are affected by certain factors and are associated with certain The occurrence of these diseases is closely related. The study of aquaporins will help to understand more about some pathophysiological mechanisms and provide new ways for the treatment of certain diseases.
