Ion channels: An open and shut case

Maria Schumacher & John P. Adelman

Top

Most ion channels open and close — they are 'gated' — in response to cues in their environment. A crystal structure of a Ca2+-gated K+-ion channel provides insight into how gating works.

Nervous systems are built for speed, using electrical signals that are propagated by the activities of ion channels. Two responsibilities are incumbent on these membrane-spanning proteins.
