Sodium channel, voltage-gated, type III, alpha subunit (SCN3A) is a protein that in humans is encoded by the Nav1.3 gene.
Voltage-gated sodium channels are transmembrane glycoprotein complexes composed of a large alpha subunit with 24 transmembrane domains and one or more regulatory beta subunits. They are responsible for the generation and propagation of action potentials in neurons and muscle. This gene encodes one member of the sodium channel alpha subunit gene family, and is found in a cluster of five alpha subunit genes on chromosome 2. Multiple transcript variants encoding different isoforms have been found for this gene.
SCN3A is the only sodium channel transcript which is changed after nerve injury.

So you won't tell me, where you've been up to now
I don't know, they've seen you come and go (oh)
You're well on your way but never leaving the chair
Playing scenes on T.V. screens
Watching widely to glimpse the full view
While the hours have their hands all over you
You say that you see me, well I see you too
I look behind, what do you find, all but an empty room
Scratching the surface and you can't get away
You've travelled far and so far you have nothing to say
[Chorus]
Scratching the surface
You better come up for air
A new experience to get you there
Scratching the surface
You better come up for air
Strapped to the media, a machine to fear
You're onto something then it slips right away
It's in your hand, follow through right in front of you
You say that you hear me, well I hear you too
My secret is no secret, outside of the tube
So you won't tell me, what you've done up to now
You're watching me, I'm watching you decide (oh)
Scratching the surface, you can't get away
You tried so hard, and so far you have nothing to say
