Description
α-Conotoxin GI is a peptide inhibitor of nicotinic acetylcholine receptors (nAChRs) originally found in species of Conus snails. α-Conotoxin GI binds nAChRs at αγ and αδ interfaces. α-Conotoxin GI decreases peak amplitude and induces tetanic and train-of-four fades, modulating acetylcholine signaling at the neuromuscular junction.
