RT Journal Article SR Electronic T1 Mammalian muscle acetylcholine receptor: a supramolecular structure formed by four related proteins JF Science JO Science FD American Association for the Advancement of Science SP 1227 OP 1229 DO 10.1126/science.7146904 VO 218 IS 4578 A1 Conti-Tronconi, BM A1 Gotti, CM A1 Hunkapiller, MW A1 Raftery, MA YR 1982 UL http://science.sciencemag.org/content/218/4578/1227.abstract AB The nicotinic acetylcholine receptor has been purified from fetal calf muscle. Amino terminal amino acid sequence data indicate that the mammalian receptor is formed from closely related but distinct subunits. A cytoskeletal component, actin, may be associated with the receptor.
