Description

Contributes to voltage-gated sodium channel activity. Predicted to be involved in membrane depolarization during action potential; neuronal action potential; and sodium ion transmembrane transport. Predicted to localize to axon and voltage-gated sodium channel complex. Used to study Dravet syndrome. Human ortholog(s) of this gene implicated in epilepsy (multiple); erythromelalgia; familial hemiplegic migraine 3; and paroxysmal extreme pain disorder. Is expressed in heart; nervous system; and neural tube. Orthologous to several human genes including SCN1A (sodium voltage-gated channel alpha subunit 1).
