target relevance
Protein names DNA topoisomerase 2-alpha (EC 5.6.2.2) (DNA topoisomerase II, alpha isozyme)
Protein family Type II topoisomerase family
Mass 174385Da
Function Key decatenating enzyme that alters DNA topology by binding to two double-stranded DNA molecules, generating a double-stranded break in one of the strands, passing the intact strand through the broken strand, and religating the broken strand (PubMed:17567603, PubMed:18790802, PubMed:22013166, PubMed:22323612). May play a role in regulating the period length of BMAL1 transcriptional oscillation (By similarity).
Catalytic activity CATALYTIC ACTIVITY: Reaction=ATP-dependent breakage, passage and rejoining of double-stranded DNA.; EC=5.6.2.2; Evidence=;
Subellular location Cytoplasm . Nucleus, nucleoplasm . Nucleus . Nucleus, nucleolus .
Tissues Expressed in the tonsil, spleen, lymph node, thymus, skin, pancreas, testis, colon, kidney, liver, brain and lung (PubMed:9155056). Also found in high-grade lymphomas, squamous cell lung tumors and seminomas (PubMed:9155056).
Structure Homodimer. Interacts with COPS5. Interacts with RECQL5; this stimulates DNA decatenation. Interacts with SETMAR; stimulates the topoisomerase activity (PubMed:18790802, PubMed:20457750). 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 (PubMed:12711669). 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 (PubMed:23652018). Interacts with ERCC6 (PubMed:26030138). Interacts with PLSCR1 (PubMed:17567603). Interacts with GCNA; this interaction allows the resolution of topoisomerase II (TOP2A) DNA-protein cross-links (By similarity). Interacts with POL1RA/RPA1 (via dock II) and UBTF in the context of Pol I complex; may assist Pol I transcription initiation by releasing supercoils occurring during DNA unwinding. Interacts with TPRN; TPRN interacts with a number of DNA damage response proteins, is recruited to sites of DNA damage and may play a role in DNA damage repair (PubMed:23213405).
Post-translational modification PTM: Phosphorylation has no effect on catalytic activity. However, phosphorylation at Ser-1106 by CSNK1D/CK1 promotes DNA cleavable complex formation.; PTM: (Microbial infection) Deubiquitinated by Epstein-Barr virus BPLF1; leading to stabilized SUMOylated TOP2A trapped in cleavage complexes, which halts the DNA damage response to TOP2A-induced double-strand DNA breaks.; PTM: SUMOylated.
