DNA topoisomerase IIα is a human enzyme encoded by the TOP2A gene. Topoisomerase IIα relieves topological DNA stress during transcription, condenses chromosomes, and separates chromatids. It catalyzes the transient breaking and rejoining of two strands of duplex DNA which allows the strands to pass through one another. The gene encoding this enzyme functions as the target for several chemotherapy agents and a variety of mutations in this gene have been associated with the development of drug resistance. Reduced activity of this enzyme may also play a role in ataxia-telangiectasia.
