New roles for old holes: ion channel function in aquaporin-1.
Review
Overview
abstract
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.
