anti-Topoisomerase (DNA) II beta 180kDa (TOP2B) Antibodies

Mouse (Murine) Topoisomerase (DNA) II beta 180kDa (TOP2B) interaction partners

1. We demonstrated that Nup98 (show NUP98 Antibodies)-TopIIbeta and Nup98 (show NUP98 Antibodies)-SETBP1 (show SETBP1 Antibodies) negatively regulate the XPO1 (show XPO1 Antibodies)-mediated protein export. Our results will contribute to the understanding of the molecular mechanism by which the Nup98 (show NUP98 Antibodies)-fusion proteins induce tumorigenesis.

2. TOP2beta as a factor involved in regulating granulosa cell genomic integrity and follicle atresia.

3. Results identified topoisomerase IIbeta (Top2beta) as a novel determinant for camptothecin sensitivity.

4. Top IIbeta might be a down-stream target of Nurr1 (show NR4A2 Antibodies), which might influence the processes of axon genesis in dopaminergic neurons via the regulation of TOP IIbeta expression.

5. Findings suggest a chromatin-based targeting of Top2beta to regulatory regions in the genome to govern the transcriptional program associated with neuronal differentiation and longevity.

6. Data suggest that activity of TOP2B in elongating spermatids is strongly inhibited by PARP1 (show PARP1 Antibodies) and PARP2 (show PARP2 Antibodies), and this is in turn counteracted by the PAR (show AFG3L2 Antibodies)-degrading activity of PAR (show AFG3L2 Antibodies) glycohydrolase.

7. proteasomal degradation of TOP2beta induced by the TOP2-DNA covalent complex or the TOP2 circular clamp is due to transcriptional arrest but not DNA damage

8. DNA topoisomerase II beta deficiency severely affects cerebral cortex stratification: no subplate is discernible, and neurons born at later stages of corticogenesis fail to migrate to the superficial layers.

9. A nuclear matrix-associated (show SMARCA5 Antibodies) topoisomerase IIB (TOP2B) interacting with an extracellular Mn2+/Ca2 (show CA2 Antibodies)+-dependent nuclease (show DCLRE1C Antibodies) cleaves sperm DNA into loop-sized fragments.

10. These results suggest that the defect in establishing neuromuscular junctions in top2beta knockout mice could be due to the lack of TopIIbeta-mediated neurite outgrowth.

Human Topoisomerase (DNA) II beta 180kDa (TOP2B) interaction partners

1. The article discusses origin of topoisomerase II beta, its structure, activities reported in vitro and in vivo along with implications in cellular processes namely transcription, DNA repair, neuronal development, aging, HIV-infection and cancer. (Review)

2. recent data point to a critical role of topoisomerase II beta (TOP2B), which is a primary target of anthracycline poisoning, in the pathophysiology of anthracycline-induced congestive heart failure .

3. The decatenation checkpoint is regulated, not only by topo IIalpha, as previously reported, but also by topo IIbeta. The decatenation checkpoint is most efficient when both isoforms are present. Deletion of most of the C-terminus of topo IIbeta, while preserving the nuclear localization signal, and mutation of Y656 in topo IIbeta inhibits the decatenation checkpoint and sensitivity to topo II (show TOP2 Antibodies)-targeted drugs.

4. TOP2B is positioned to solve topological problems at diverse cis-regulatory elements and its occupancy is a highly ordered and prevalent feature of CTCF/cohesin binding sites that flank TADs.

5. Data indicate that cortex involvement, lower World Health Organization grade and DNA topoisomerase II (show TOP2 Antibodies) positivity were strong predictors for preoperative epileptic seizures.

6. during early development, TOP2A (show TOP2A Antibodies) is likely to have a role in cell proliferation, whereas TOP2B is expressed in post-mitotic cells and may be important in controlling expression of long genes even at this early stage.

7. Cinobufacini inhibited the proliferation of the HepG-2 cells induced apoptosis in a dose- and time-dependent manner and downregulated the mRNA and protein expression levels of TOPO I (show TOP1 Antibodies) and TOPO II (show TOP2 Antibodies)

8. A direct interaction between Ku70 (show XRCC6 Antibodies)/86 and BRG1 (show SMARCA4 Antibodies) brings together SWI (show SMARCA1 Antibodies)/SNF (show SNRPA Antibodies) remodeling capabilities and TOP2beta activity to enhance the transcriptional response to hormone stimulation.

9. Human cytomegalovirus IE1 exon 4 interacts with Topoisomerase IIbeta (TOPOIIbeta), whose activity is required for viral genome persistence and maintenance via binding to a cis (show CISH Antibodies)-acting viral maintenance element.

10. Proteolytic degradation of Top2 (show TOP2A Antibodies) enables the processing of Top2 (show TOP2A Antibodies).DNA and Top2 (show TOP2A Antibodies).RNA covalent complexes by TDP2 (show TDP2 Antibodies).
