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, respond to acetylcholine, they respond to other molecules as well. Nicotinic … See more An acetylcholine receptor (abbreviated AChR) is an integral membrane protein that responds to the binding of acetylcholine, a neurotransmitter. See more Molecular biology has shown that the nicotinic and muscarinic receptors belong to distinct protein superfamilies. Nicotinic receptors are of … See more Nicotinic acetylcholine receptors can be blocked by curare, hexamethonium and toxins present in the venoms of snakes and shellfishes, like α-bungarotoxin. Drugs such as the neuromuscular blocking agents bind reversibly to the nicotinic receptors in the See more ACh receptors are related to GABA, glycine, and 5-HT3 receptors and their similar protein sequence and gene structure strongly suggest … See more • Muscarinic acetylcholine receptor M5 • Nicotinic agonists See more • Acetylcholine receptor: PMAP The Proteolysis Map-animation • Acetylcholine+Receptors at the U.S. National Library of Medicine Medical Subject Headings (MeSH) • Acetylcholine Receptor: Molecule of The Month by David Goodsell See more WebDiffuse extrajunctional acethycholine receptors (AChR) of skeletal muscle fibers were readily visualized by light and electron microscopy in muscle biopsy specimens of …
