Motion in Nicotinic Acetylcholine Receptor [achr]

[ jump to morphs ]

Classification Suspected Fragment Motion, Unclassifiable [F-?-1]

Description
A motion of transmembrane helices is seen in low-resolution images of the nicotinic acetylcholine receptor (10). This gated ion channel has five subunits, and the channel is lined by a helix from each of them. Binding of acetylcholine ~35 A away from the membrane leads to substantial rearrangements that switch the channel-lining helices to an alternative association and open the channel.
