  • 7692
Name DNA topoisomerase 2-beta
Synonyms
  1. DNA topoisomerase II, beta isozyme
Gene Name TOP2B
Protein Type Enzyme
Biological Properties
General Function Involved in sequence-specific DNA binding transcription factor activity
Specific Function Control of topological states of DNA by transient breakage and subsequent rejoining of DNA strands. Topoisomerase II makes double-strand breaks. Indirectly ivolved in vitamin D- coupled transcription regulation via its association with the WINAC complex, a chromatin-remodeling complex recruited by vitamin D receptor (VDR), which is required for the ligand-bound VDR- mediated transrepression of the CYP27B1 gene
