摘要：
The nicotinic acetylcholine receptor behaves as an allosteric protein with multipole, interconvertible conformations: a resting state, an open channel state and several desensitized states. A variety of pharmological agents and physiological ligands regulate the transitions between these states when they bind to sites topographically distinct from the acetylcholine binding site. The physiological significance of this type of regulation is discussed and its potential role in the modulation of synaptic efficacy suggested.
