TOPBP1 (DNA Topoisomerase II Binding Protein 1) is a Protein Coding gene. Diseases associated with TOPBP1 include Anogenital Venereal Wart. Among its related pathways are DNA Damage and DNA Double-Strand Break Repair. TOPBP1 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.
