Title α-Conotoxin GIC from Conus geographus, a novel peptide antagonist of nicotinic acetylcholine receptors
Date 2002
Description Many venomous organisms produce toxins that disrupt neuromuscular communication to paralyze their prey. One common class of such toxins comprises nicotinic acetylcholine receptor antagonists (nAChRs). Thus, most toxins that act on nAChRs are targeted to the neuromuscular subtype. The toxin characterized in this report, α-conotoxin GIC, is a most striking exception. The 16-amino acid peptide was identified from a genomic DNA clone from Conus geographus.
