Activity

Neurotoxin
FUNCTION: Iota-conotoxins bind to voltage-gated sodium channels (Nav) and act as agonists by shifting the voltage-dependence of activation to more hyperpolarized levels. Produces general excitatory symptoms (By similarity). {ECO:0000250}.

Target

voltage-gated sodium channel (Nav)
