アクアポリン

Also known as water channel, Aquaporin transporter, Aquaporin_transptr, IPR034294, aquaporins

Aquaporins, also called water channels, are channel proteins from a larger family of major intrinsic proteins that form pores in the membrane of biological cells, mainly facilitating transport of water between cells. The cell membranes of a variety of different bacteria, fungi, animal and plant cells contain aquaporins through which water can flow more rapidly into and out of the cell than by diffusing through the phospholipid bilayer. Aquaporins have six membrane-spanning α-helical domains with both carboxylic and amino terminals on the cytoplasmic side. Two hydrophobic loops contain conserve
