靶点详情

  • 功能：
    Releases the supercoiling and torsional tension of DNA introduced during the DNA replication and transcription by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA-(5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand than undergoes passage around the unbroken strand thus removing DNA supercoils. Finally, in the religation step, the DNA 3'-OH attacks the covalent intermediate to expel the active-site tyrosine and restore the DNA phosphodiester backbone. Possesses negatively supercoiled DNA relaxing activity.
  • 基因功能参考文献：
    1. Structural basis of the interaction between TOP3B and the TDRD3 auxiliary factor has been reported. PMID: 28176834
    2. Results identified TOP3B gene deletion as candidate gene in the etiology of neurodevelopmental disorders including juvenile myoclonic epilepsy. PMID: 29490292
    3. Top3beta mutants lacking either its RNA-binding domain or catalytic residue fail to promote synapse formation, suggesting that Top3beta requires both its mRNA-binding and catalytic activity to facilitate neurodevelopment. PMID: 28039324
    4. Top3b proteins from several animals associate with polyribosomes, which are units of mRNA translation, whereas the Top3 homologs from E. coli and yeast lack the association. The Top3b-polyribosome association requires TDRD3, which directly interacts with Top3beta and is present in animals but not bacteria or yeast. PMID: 27257063
    5. TOP3B promotes transcription, protects against DNA damage, and reduces the frequency of chromosomal translocations. PMID: 24507716
    6. Topoisomerase IIIbeta expression can be a useful marker in assessing the prognosis of patients with breast cancer and is an independent predictor of survival. PMID: 20950730
    7. the positive regulatory region including the 5'GGAACC3' core element is essential for efficient expression of the DNA topoisomerase III beta gene PMID: 15358519
    8. Two isoforms of human DNA topoisomerase IIIbeta were expressed in HeLa cells. Isoform 1 was localized to the nucleus and associated with chromosomes during metaphase and anaphase. Isoform 2 was found in the cytoplasm. PMID: 11549288
