TTF2 has been shown to have dsDNA-dependent ATPase activity and RNA polymerase II termination activity. This protein interacts with cell division cycle 5-like, associates with human splicing complexes, and plays a role in pre-mRNA splicing.The deduced 990-amino acid TTF2 protein shares 43% amino acid sequence identity with Drosophila factor 2. These proteins contain 7 motifs found in helicase superfamilies 1 and 2; 7 additional motifs shared only by SWI2/SNF2 family members; and 3 conserved motifs and a nuclear localization signal that are not conserved among the SWI2/SNF2 family. Similar to Drosophila factor 2, recombinant human TTF2 displayed a strong double-stranded DNA-dependent ATPase activity that was inhibited by single-stranded DNA and exhibited RNA polymerase II termination activity.
Human Transcription termination factor 1 (TTF1) ELISA Kit employs a two-site sandwich ELISA to quantitate TTF1 in samples. An antibody specific for TTF1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTTF1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TTF1 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of TTF1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
