<unk>  is a long chain neuropeptide belonging to the scorpion toxin superfamily.<unk>  is classified as a member of the beta-toxin subfamily. The global secondary structure of<unk>  is similar to that of other scorpion beta-toxins, including the alpha-helix, triple stranded antiparallel beta-sheet, and the four disulfide bridges. The higher affinity for crustacean rather than mammalian sodium channels has been attributed to the presence of Trp18, a hydrophobic amino acid at the surface of<unk> .
