== Function ==
[https://www.uniprot.org/uniprot/O16A_CONGE O16A_CONGE] Omega-conotoxins act at presynaptic membranes, they bind and block voltage-gated calcium channels (Cav). This toxin blocks N-type calcium channels (Cav2.2/CACNA1B) with a high potency (it displaces [125I]GVIA with an IC(50)=3.7-38 pM) (PubMed:10938268, PubMed:11724570).<ref>PMID:10938268</ref> <ref>PMID:11724570</ref>
