Complex organisms regulate the osmolalities of their compartments by limiting water flow across some membranes and promoting rapid water flow across others via proteins called aquaporins. Barrier epithelia limit water flow by reducing the mobilities of fatty acid chains in their apical membranes, especially in the outer leaflets of these membranes. Aquaporins are 28 to 30 kDa, 6 membrane-spanning proteins that are expressed in a wide variety of organisms from bacteria to plants to mammals. The… CONTINUE READING
