Jingzhaotoxin-V

Jingzhaotoxin-V, a 29-residue polypeptide, is derived from the venom of the spider Chilobrachys jingzhao. Jingzhaotoxin-V inhibits tetrodotoxin-resistant and tetrodotoxin-sensitive sodium currents in rat dorsal root ganglion neurons with IC50 values of 27.6 nM and 30.2 nM, respectively. Jingzhaotoxin-V also inhibits Kv4.2 potassium currents expressed in Xenpus Laevis oocytes (IC50 of 604.2 nM) [1].
