Never at rest: insights into the conformational dynamics of ion channels from cryo-electron microscopy.

Never at rest: insights into the conformational dynamics of ion channels from cryo-electron microscopy.
Eduardo Perozo, Mark J Hunter, Jamie I Vandenberg, Carus Lau, Alastair Stewart
The tightly regulated opening and closure of ion channels underlies the electrical signals that are vital for a wide range of physiological processes. Two decades ago the first atomic level view of ion channel structures led to a detailed understanding of ion selectivity and conduction. In recent years spectacular developments in the field of cryo-electron microscopy have resulted in cryo-EM superseding crystallography as the technique of choice for determining near atomic resolution structures of ion channels. Here, we will review the recent developments in cryo-EM and its specific application to the study of ion channel gating. We will highlight the advantages and disadvantages of the current technology and where the field is likely to head in the next few years. This article is protected by copyright. All rights reserved.
