FUNCTION: Pore-forming subunit of a voltage-gated sodium channel complex through which Na(+) ions pass in accordance with their electrochemical gradient. Alternates between resting, activated and inactivated states (PubMed:12766226, PubMed:29992740, PubMed:30190309, PubMed:15318338, PubMed:16890191,...
