Functional gene description: Tankyrase (TNKS) is a ovel gene with homology to both ankyrins and the cataytic domain of poly(ADP-ribose) polymerase (PARP) that as recently cloned using a yeast two-hybrid screen with he telomere-specific DNA binding protein TRF1 (1). ankyrase protein is located at telomeres, centrosomes, nd nuclear pore complexes (1; S. Smith and T. de Lange, n preparation). In v...
Telomeres are regulated by a homeostatic mechanism that includes telomerase and telomeric repeat binding proteins, TRF1 and TRF2. Recently, it has been hypothesized that telomeres assume distinct configurations in a cell-cycle-dependent manner, although direct biochemical evidence is lacking. Here we demonstrated that Xenopus TRF1 (xTRF1) associates with telomere chromatin specifically in mitot...
Added by telomerase, arrays of TTAGGG repeats specify the ends of human chromosomes. A complex formed by six telomere-specific proteins associates with this sequence and protects chromosome ends. By analogy to other chromosomal protein complexes such as condensin and cohesin, I will refer to this complex as shelterin. Three shelterin subunits, TRF1, TRF2, and POT1 directly recognize TTAGGG repe...
