Aquaporin - an overview ScienceDirect Topics

WebAquaporins (AQP) are integral membrane proteins that serve as channels in the transfer of water, and in some cases, small solutes across the membrane. They are conserved in bacteria, plants, and animals. Structural analyses of the molecules have revealed the presence of a pore in the center of each aquaporin molecule. WebAQP9 may transport other small, polar solutes as well, including amino acids, sugars, and even arsenite (1, 2).
