The conformational changes underlying cysteine-loop receptor channel gating remain elusive and controversial. We previously developed a single-channel electrophysiological method that allows structural inferences about the transient open-channel conformation to be made from the effect and properties of introduced charges on systematically engineered ionizable amino acids. Here we have applied this methodology to the entire M1 and M3 segments of the muscle nicotinic acetylcholine receptor, two… CONTINUE READING
