Tankyrase Definition
Tankyrase, a protein containing 24 ankyrin repeats and homology to the catalytic domain of PARP, is localized to human telomeres. The tankyrase ankyrin domain interacts with TRF1, which regulates telomere length by inhibiting telomerase. Tankyrase may have PARP activity and may function as acceptor for adenosine diphosphate (ADP)-ribosylation. Tankyrase may act as a positive regulator of telomere elongation by inhibiting TRF1; tankyrase-mediated ADP-ribosylation of TRF1 may open the telomeric complex, allowing access to telomerase. Tankyrase gene was mapped to 8p23.1. (from OMIM 603303 and NCI)
