| Function |
Pore-forming subunit of a voltage-gated sodium channel complex through which Na(+) ions pass in accordance with their electrochemical gradient (PubMed:2559760, PubMed:16303569, PubMed:28012039). Alternates between resting, activated and inactivated states (PubMed:28012039). Required for normal muscle fiber excitability, normal muscle contraction and relaxation cycles, and constant muscle strength in the presence of fluctuating K(+) levels (By similarity).
