TRF-2 (telomeric repeat-binding factor 2; also telomeric DNA-binding protein) is a 55-60kD, ubiquitously expressed nuclear protein that participates in telomere homeostasis.
TRF-2 binds as a dimer to TTAGGG repeats at ends of chromosomes (telomeres), where it blocks inappropriate activation of the ATM/p53 pathway.
It also collaborates with TRF-1 to promote normal telomere length.
TRF2 has been found up regulated in several human cancers.
Human TRF-2 is 500 aa in length.
It contains an N-terminal Arg-rich region (aa13-30), a dimerization domain (aa46-112), an NLS (aa329-333), and a DNA binding HTH myb-type domain (aa442-499).
There is one potential alternate start site 42aa upstream of the standard start site, and one splice form that shows a 13aa substitution for aa239-500.
Over aa78-238, human TRF-2 shares 96% aa identity with mouse TRF-2.
