This toxin reduces the outward currents that are due to the opening of voltage-gated potassium channels in DRG neurons. In addition, leftward shift in the presence of this toxin is observed in averaged normalized conductance-voltage plot of outward sodium currents (Nav1.2/SCN2A). Expressed by the venom duct. The cysteine framework is XXXII (C-CC-C-C-C). Exists in two forms, due to cis-trans isomerization at 23-Asp-Pro-24.
