Non-specific lipid-transfer protein also known as sterol carrier protein 2 (SCP-2) or propanoyl-CoA C-acyltransferase is a protein that in humans is encoded by the SCP2 gene.
This gene encodes two proteins: sterol carrier protein X (SCPx) and sterol carrier protein 2 (SCP2), as a result of transcription initiation from 2 independently regulated promoters. The transcript initiated from the proximal promoter encodes the longer SCPx protein, and the transcript initiated from the distal promoter encodes the shorter SCP2 protein, with the 2 proteins sharing a common C-terminus. Evidence suggests that the SCPx protein is a peroxisome-associated thiolase that is involved in the oxidation of branched chain fatty acids, while the SCP2 protein is thought to be an intracellular lipid transfer protein. Alternative splicing of this gene produces multiple transcript variants, some encoding different isoforms. The full-length nature of all transcript variants has not been determined.
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
