Gene Gene information from NCBI Gene database.
Entrez ID 7155
Gene name DNA topoisomerase II beta
Gene symbol TOP2B
Synonyms (NCBI Gene)
BILUTOPIIBtop2beta
Chromosome 3
Chromosome location 3p24.2
Summary This gene encodes a DNA topoisomerase, an enzyme that controls and alters the topologic states of DNA during transcription. This nuclear enzyme is involved in processes such as chromosome condensation, chromatid separation, and the relief of torsional str
