TOP2A
Control of topological states of DNA by transient breakage and subsequent rejoining of DNA strands. Topoisomerase II makes double-strand breaks. Essential during mitosis and meiosis for proper segregation of daughter chromosomes. May play a role in regulating the period length of ARNTL/BMAL1 transcriptional oscillation. Belongs to the type II topoisomerase family. 4 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
