The p14ARF alternate reading frame protein enhances DNA binding of topoisomerase I by interacting with the serine 506-phosphorylated core domain.
In addition to its well-characterized function as a tumor suppressor, p14ARF (ARF) is a positive regulator of topoisomerase I (topo I), a central enzyme in DNA metabolism and a target for cancer therapy. We previously showed that topo I hyperphosphorylation, a cancer-associated event mediated by ele...
