Human Topoisomerase (DNA) III alpha (TOP3A) interaction partners

1. Top3alpha is shown to be an essential component of the mitochondrial DNA replication machinery and as the first component of the mitochondrial DNA separation machinery.

2. The results show that Topo IIIalpha stimulates DNA unwinding by BLM in a manner that is potentiated by RMI1-RMI2, and that the processivity of resection is reliant on the Topo IIIalpha-RMI1-RMI2 complex.

3. hTOP3alpha interacts with p53, regulates p53 and p21 expression, and contributes to the p53-mediated tumor suppression

4. MPS1 protein-dependent phosphorylation of RecQ-mediated genome instability protein 2 (RMI2) at serine 112 is essential for BLM-Topo III alpha-RMI1-RMI2 (BTR) protein complex function upon spindle assembly checkpoint (SAC) activation during mitosis

5. Study found a correlation between topoisomerase IIIalpha immunoexpression and oral squamous cell carcinoma (OSCC) cancer stem cell immunophenotypes. However, results did not show a prognostic significance of topoisomerases in OSCC>

6. TOP3A, a new partner gene fused to MLL in an adult patient with de novo acute myeloid leukaemia.

7. human topoisomerase IIIalpha functions as a decatenase with the assistance of BLM and RMI1 to facilitate the processing of homologous recombination intermediates without crossing over as a mechanism to preserve genome integrity

8. G-quadruplex ligand telomestatin impairs binding of topoisomerase IIIalpha to G-quadruplex-forming oligonucleotides and uncaps telomeres in ALT cells

9. Dual localization to mitochondria and nucleus

10. The Bloom's syndrome helicase stimulates the activity of topoisomerase IIIalpha

11. The effects of TOP3 on telomere binding in human and S. cerevisiae cells are reported.

12. BLM, Topo IIIalpha, and BLAP75 constitute a dissolvasome complex that processes HR intermediates to limit DNA crossover formation

13. BLM is stably associated with TOP3A.

14. evolutionarily conserved N-terminal third of BLAP75 mediates complex formation with BLM and Topo IIIalpha and that the DNA binding activity resides in the C-terminal third of this novel protein.

15. Topo IIIalpha is an important telomere-associated factor, essential for telomere maintenance and chromosome stability in ALT cells, and speculate on its potential mechanistic function.

16. Individuals carrying genetic variants of the BLM-TOP3A-RMI1 complex have an increased risk of acute myeloid leukemia/myelodysplatic syndromes, malignant melanoma, bladder and breast cancer.
