High-resolution structure of a #fish #aquaporin reveals a novel extracellular fold https://www.life-science-alliance.org/content/5/12/e202201491
By studying the #aquaporins in the cells of the #ClimbingPerch Anabas testudineus, which sometime climb out of the water and spend time on land, researchers have identified a water channel that appears to have a unique quick-closing valve.
Quick-closing valve allows fish to rapidly regulate the water in their cells
Regulating the fluid balance in cells is vital in all living things. When insufficient water is being transported via the cell membrane, cells can use their aquaporins—also known as water channels—that open and close to remedy this. Researchers at the University of Gothenburg recently identified a water channel in a fish with what appears to be a unique quick-closing valve. Ultimately, this discovery could be significant in the development of drugs to treat cancer and Alzheimer's disease.
