Alpha-conotoxins act on postsynaptic membranes, they bind to the nicotinic acetylcholine receptors (nAChR) and thus inhibit them. This toxin inhibits alpha-3-beta-4, alpha-6/alpha-3-beta-4, and alpha-2-beta-4 nAChRs. Expressed by the venom duct. The cysteine framework is I (CC-C-C). Alpha4/6 pattern. This toxin does not show inhibition at neuronal alpha-4-beta-4, alpha-4-beta-2, alpha-6/alpha-3-beta-2-beta-3, alpha-3-beta-2, alpha-2-beta-2, alpha-9-alpha-10, alpha-7 nAChRs and muscle alpha-1-beta-1-delta-epsilon nAChR. Belongs to the conotoxin A superfamily.
