Alpha-conotoxins act on postsynaptic membranes, they bind to the nicotinic acetylcholine receptors (nAChR) and thus inhibit them. Synthetic peptide inhibits alpha-6/alpha-3/beta-2 and alpha-3/beta-2 nicotinic acetylcholine receptors and causes uncoordinated movement when intramuscularly injected into goldfish (PubMed:18588930). Has a distinct nAChR binding mode from other alpha-conotoxins, due to a different three residue motif (Ala-Xaa-Ala instead of the conserved Ser-Xaa-Pro motif) (By similarity). Expressed by the venom duct. The cysteine framework is I (CC-C-C). Alpha4/7 pattern. Belongs to the conotoxin A superfamily.
