WebTDP2 was previously shown to be involved in cell survival after treatment with TOP2 poisons (5,6). Schellenberg et al.’s research provides a clearer picture of exactly how TDP2 associates with TOP2 when resolving TOP2cc, how its activity helps increase cell survivability when being treated with TOP2 poisons, and the extent to which SUMOs and ...
