Number of residues	2000
Molecular Weight	226291.905
Theoretical pI	5.49
GO Classification	Functions voltage-gated sodium channel activity Processes sodium ion transport sodium ion transmembrane transport membrane depolarization during action potential neuronal action potential Components cytoplasm voltage-gated sodium channel complex plasma membrane
General Function	Voltage-gated sodium channel activity
Specific Function	Mediates the voltage-dependent sodium ion permeability of excitable membranes. Assuming opened or closed conformations in response to the voltage difference across the membrane, the protein forms a sodium-selective channel through which Na(+) ions may pass in accordance with their electrochemical gradient.
