Alpha-conotoxins act on postsynaptic membranes, they bind to the nicotinic acetylcholine receptors (nAChR) and thus inhibit them (By similarity). Expressed by the venom duct. The cysteine framework is I (CC-C-C). Alpha4/4 pattern. Does not inhibits high voltage-activated (HVA) calcium channel currents in rat DRG neurons (at 1 uM toxin) (PubMed:26948522). Belongs to the conotoxin A superfamily. The synthetic peptide described in PubMed:26948522 shows the toxin without C-terminal amidation.
