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 . Plays a key role in brain; probably by regulating the moment when neurotransmitters are released in neurons. Involved in sensory perception of mechanical pain: activation in somatosensory neurons induces pain without neurogenic inflammation and produces hypersensitivity to mechanical; but not thermal stimuli.
