The Poly ADP-ribose polymerase family is a series of enzymes, where the best characterised members are nuclear proteins which are thought to function by binding to single strand breaks in DNA, allowing the recruitment of repair enzymes by the synthesis of NAD-derived ADP-ribose polymers, which are subsequently degraded by a glycohydrolase (PARG, Q86W56). The most well defined function of the tankyrases (TNKSs) is their regulatory action on Wnt/β-catenin signalling [2].
