TOPBP1 Gene Information

HGNC symbol
TOPBP1 
Aliases
Dpb11; KIAA0259; TOP2BP1 
Common name
DNA topoisomerase II binding protein 1 
Entrez Id
11073
Description
This gene encodes a binding protein which interacts with the C-terminal region of topoisomerase II beta. This interaction suggests a supportive role for this protein in the catalytic reactions of topoisomerase II beta through transient breakages of DNA strands. [provided by RefSeq, Jul 2008].
