Research Backgrounds

Function:

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 (By similarity).

PTMs:

Phosphorylation has no effect on catalytic activity. However, phosphorylation at Ser-1106 by CSNK1D/CK1 promotes DNA cleavable complex formation.

Subcellular Location:

Cytoplasm. Nucleus>Nucleoplasm.
Note: Generally located in the nucleoplasm.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
Subunit Structure:

Homodimer. Interacts with COPS5. Interacts with RECQL5; this stimulates DNA decatenation. Interacts with SETMAR; stimulates the topoisomerase activity. Interacts with DHX9; this interaction occurs in a E2 enzyme UBE2I- and RNA-dependent manner, negatively regulates DHX9-mediated double-stranded DNA and RNA duplex helicase activity and stimulates TOP2A-mediated supercoiled DNA relaxation activity. Interacts with HNRNPU (via C-terminus); this interaction protects the topoisomerase TOP2A from degradation and positively regulates the relaxation of supercoiled DNA in a RNA-dependent manner (By similarity). Interacts with MCM3AP isoform GANP. Interacts with ERCC6.

Family&Domains:

The N-terminus has several structural domains; the ATPase domain (about residues 1-265), the transducer domain (about 266-428) and the toprim domain (455-572) (PubMed:25202966). Comparing different structures shows ATP hydrolysis induces domain shifts in the N-terminus that are probably part of the mechanism of DNA cleavage and rejoining (PubMed:25202966).

Belongs to the type II topoisomerase family.
