Effects of JZTX-V on the wild type Kv4.3 Expressed in HEK293T and Molecular Determinants in the Voltage-sensing Domains of Kv4.3 Interacting with JZTX-V.

JZTX-V is a toxin isolated from the venom of the Chinese spider . Previous studies had shown that JZTX-V could inhibit the transient outward potassium current of Kv4.2 and Kv4.
