TOPBP1
DNA topoisomerase 2-binding protein 1 is an enzyme that in humans is encoded by the TOPBP1 gene.
Function
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.
Interactions
TOPBP1 has been shown to interact with:
E2F1,
Promyelocytic leukemia protein,
RAD9A,
UBR5, and
ZBTB17
Clinical relevance
This gene may be involved in the development of ovarian and breast cancer.
Mutations in TOPBP1 cause Idiopathic pulmonary arterial hypertension .
