TOP2B Control of topological states of DNA by transient breakage and subsequent rejoining of DNA strands. Topoisomerase II makes double-strand breaks. Belongs to the type II topoisomerase family. 2 alternatively spliced human isoforms have been reported. Note: This description may include information from UniProtKB.
