WebJun 6, 2013 · Muscarinic acetylcholine receptors, which comprise five subtypes (M 1-M 5 receptors), are expressed in both the CNS and PNS (particularly the target organs of parasympathetic neurons). M 1-M 5 receptors are integral membrane proteins with seven transmembrane segments, bind with acetylcholine (ACh) in the extracellular phase, and … WebAug 6, 1996 · Abstract. Ligands that bind to the allosteric-binding sites on muscarinic acetylcholine receptors alter the conformation of the classical-binding sites of these receptors and either diminish or increase their affinity for muscarinic agonists and classical antagonists. It is not known whether the resulting conformational change also affects the ...
