RESUMO
TNKSs are members of poly ( ADPribose) polymera-ses, which are different from other members of the PARP family with two unique structures: SAM domain and ankyrin repeat re-gion. TNKS participates in a variety of cellular function regula-tion, including telomere’ s dynamic balance, Wnt signaling pathways, glucose metabolism and spindle formation during mi-tosis. TNKS, as a very attractive drug target, regulates the sta-bility of target proteins via poly ( ADP-ribosylation). In recent years, the significant progress has been made for PARP inhibi-tors in cancer treatment. Multiple PARP inhibitors have entered different clinical evaluation stages. AstraZeneca's Olaparib, Clo-vis's Rucaparib, Merck's Niraparib come into existence in the market. This paper summarizes the recent studies of TNKS and its related inhibitors.
