Ion channels: An open and shut case
Maria Schumacher & John P. Adelman
Abstract
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.
- Maria Schumacher is in the Department of Biochemistry and Molecular Biology, and John P. Adelman is at the Vollum Institute, Oregon Health and Sciences University, Portland, Oregon 97201, USA
