Background
DNA topoisomerases are ubiquitous nuclear enzymes that alter the topology of DNA. Topoisomerase I produces transient single-stranded breaks in DNA, while topoisomerase II produces transient double-stranded breaks in DNA. These DNA breaks are important for DNA replication and chromosome condensation and segregation. Two types of topoisomerase II have been identified, TopoIIalpha and TopoIIbeta. During interphase, TopoIIalpha is found in the nucleoplasm and nucleoli, and in mitosis, TopoIIalpha is found associated with metaphase chromosomes and centromeres. Transcriptional control of TopoIIalpha expression is regulated through multiple gene promoters, which include five inverted CCAAT boxes, one ATF binding sequence, and two GC-rich boxes. ICBP90 was identified in one-hybrid screen of proteins that can bind an inverted CCAAT box. ICBP90 is expressed highest in proliferative tissues such as thymus, liver, and bone marrow. Overexpression of ICBP90 in COS-1-transfected cells leads to enhanced expression of TopoIIalpha. ICBP90 co-localizes with TopoIIalpha in proliferating areas of appendix and in high grade breast carcinomas. Thus, ICBP90 may be an important transcripitonal regulator of TopoIIalpha expression in proliferating cells.
