For many years, it was thought that water movement into and out of the cell was (1) not regulated in any manner and (2) could be accounted for by simple diffusion across the cell membrane. However, the rapid movement of water in aqueous ...

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.
