Iota-conotoxin-like Fi11.6

Gene
N/A
Organism
Conus figulinus (Fig cone)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Experimental evidence at transcript leveli

Functioni

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).By similarity
