Telomeric repeat-binding factor 1 is a protein that in humans is encoded by the TERF1 gene.[1][2]
This gene encodes a telomere specific protein which is a component of the telomere nucleoprotein complex. This protein is present at telomeres throughout the cell cycle and functions as an inhibitor of telomerase, acting in cis to limit the elongation of individual chromosome ends. The protein structure contains a C-terminal Myb motif, a dimerization domain near its N-terminus and an acidic N-terminus. Two transcripts of this gene are alternatively spliced products.[2]

TERF1 has been shown to interact with SALL1,[3] MAPRE1,[4] NME1,[5] TNKS2,[6][7][8] Ataxia telangiectasia mutated,[9] TINF2,[10][11][12] TNKS,[6][8][13][14][15] PINX1[16] and Abl gene.[9]

Trophy Wife
by: NationalNo nobody wants to be
no no one's lover
no matter what they say
lovers know they are the ones
who one day have to go
trophy wives
I know they wander
and find a young young man
trophy wives
I know they wander
one time you were a good rabbit
to all the girls
and all their lovely mothers
you tried a piece of everything
now nothing turns you on
trophy wives
I know they wander
and find a young young man
trophy wives
I know they wander
run run baby I don't feel alive
but I'm pretty and I'm pretty sure
I'm gonna be alright to drive
to new jack city for a younger man
with a better brain
I fell in love with you
no matter what you say
but you were right about the reasons
I don't want to be
what I'm becoming
your trophy wife
I know they wander
and find a young young man
you trophy wife
I know they wander
and find a young man
your trophy wife
