[[https://www.uniprot.org/uniprot/CI1BA_CONRA CI1BA_CONRA]] Iota-conotoxins bind to voltage-gated sodium channels and act as agonists by shifting the voltage-dependence of activation to more hyperpolarized levels. This toxin acts on Nav1.6/SCN8A > Nav1.2/SCN2A > Nav1.7/SCN9A sodium channels. Produces general excitatory symptoms upon intracorporeal injection and repetitive action potentials in the frog cutaneous pectoris muscle. Natural peptide (with D-Phe) is active on nerve, but not on muscle. Synthetic peptide (with L-Phe) is not active on both nerve and muscle.<ref>PMID:17696362</ref> <ref>PMID:18486102</ref>
