Structural and mutagenesis studies indicate that aquaporin monomers assemble in membrane as tetramers in which each monomer contains an independent water pore 有关研究表明,水通道蛋白的单体是以四聚体的形式嵌入细胞膜中,在每一个单体中包含一个独立的水通道。

Aquaporin ( water pore ) a protein channel in the plasma membrane that facilitates water movement across the membrane . aquaporins can open or close to increase or decrease water flow 水通道(水孔) :位于质膜上的一种蛋白通道,控制水的跨膜运输。它的开或关可以增加或减少水的流量。
