UniProtKB description:  Gating-modifier toxin that inhibits voltage-gated sodium channel with a preference for hNav1.7/SCN9A (IC(50)=25.4 nM) over hNav1.1/SCN1A (IC(50)=4.1 uM), hNav1.2/SCN2A (IC(50)=813 nM), and hNav1.6/SCN8A (IC(50)=15.2 uM) (PubMed:24082113). Is an effective analgesic in rodent pain models, since it is several-fold more effective than morphine in a rodent model of formalin-induced pain and is equipotent with morphine in its ability to reduce thermal and acid-induced pain (PubMed:24082113). In addition, this peptide shows a high level of resistance to proteases and a high thermal stability that may be explained by its predominant composition of alpha-helices (PubMed:24082113).
