New roles for old holes: ion channel function in aquaporin-1.
Mammalian aquaporins are part of the diverse major intrinsic protein family of water and solute channels. Intriguing links exist in structural and functional properties between aquaporins and ion channels. A novel role for aquaporin-1 as a gated ion channel reshapes our current views of this ancient family of transmembrane channel proteins.
