WebApr 10, 2024 · Here, we demonstrate that the ubiquitin ligase RFWD3, whose mutation causes Fanconi Anemia, promotes recruitment of the DNA translocase ZRANB3 to stalled replication forks and ubiquitinated sites of DNA damage. Using electron microscopy, we show that RFWD3 stimulates fork remodeling in a ZRANB3-epistatic manner. WebDNA inter-strand cross-links are caused by endogenous metabolites and cancer chemotherapeutics, and their repair is crucial to suppress cancer and bone marrow failure.
