Tankyrase 1 Proteins and Enzymes

The ~142 kDa Tankyrase protein is ubiquitously expressed in mammalian cells and is localized to human telomeres. It has homology to ankyrins and to the catalytic domain of poly (adenosine diphosphate-ribose) polymerase (PARP). Tankyrase binds to TRF1 (telomeric repeat binding factor-1), which negatively regulates the maintenance of telomere lengt...
