Ion channels: Gate expectations
Maria L. Garcia1
Abstract
The opening and closing — gating — of ion channels in response to specific stimuli is crucial for cell function. The membrane-partitioning activities of two venom toxins give insights into the mechanisms involved.
The membrane surrounding a biological cell forms a highly selective barrier that allows the cell to control its internal environment. It consists of an assembly of lipids and proteins.
