Activity

Neurotoxin
FUNCTION: Binds specifically to voltage-gated sodium channels (Nav), thereby delaying their inactivation during signal transduction (By similarity). Stimulates mammalian heart contraction (PubMed:14672713). {ECO:0000250, ECO:0000269|PubMed:14672713}.

Target

voltage-gated sodium channel (Nav)
