(Reprinted, with permission, from Martyn JAJ, White DA, Gronert GA, et al. Up-and-down regulation of skeletal muscle acetylcholine receptors. Although all acetylcholine receptors, by definition, respond to acetylcholine, they respond to other molecules as well. Nicotinic acetylcholine receptors ( nAChR, also known as "ionotropic" acetylcholine receptors) are particularly responsive to nicotine. The nicotine ACh receptor is also a Na +, K + and Ca … Zobacz więcej An acetylcholine receptor (abbreviated AChR) is an integral membrane protein that responds to the binding of acetylcholine, a neurotransmitter. Zobacz więcej Like other transmembrane receptors, acetylcholine receptors are classified according to their "pharmacology," or according to their relative affinities and sensitivities to different molecules. Although all acetylcholine receptors, by definition, … Zobacz więcej ACh receptors are related to GABA, glycine, and 5-HT3 receptors and their similar protein sequence and gene structure strongly suggest that they evolved from a common ancestral receptor.
