Neurotoxin
FUNCTION: Inhibits tetrodotoxin-sensitive voltage-gated sodium channels (TTX-S Nav) in rat dorsal root ganglion (DRG) neurons in a concentration- and voltage-dependent manner. Lowers the activation threshold and produces negative shifting of TTX-S sodium current activation curve. Induces shifting of the steady-state inactivation curve to the left, delays the recovery of TTX-S I(Na) from inactivation. {ECO:0000269|PubMed:19199142}.
