Michael | New α-conotoxin which targets α3ß2 nicotinic acetylcholine receptors | We have isolated a 16-amino acid peptide from the venom of the marine snail Conus magus which potently blocks nicotinic acetylcholine receptors (nAChRs) composed of α3ß2 subunits. This peptide, named a-conotoxin MII, was identified by electrophysiologically screening venom fractions against cl... | Conotoxins; a-conotoxin MII; Conus magus | 1996 |
