DNA2 nuclease/helicase is a structure-specific nuclease, 5′-to-3′ helicase, and DNA- dependent ATPase. It is involved in multiple DNA metabolic pathways, including Okazaki …
A universal response to replication stress is replication fork reversal, where the nascent complementary DNA strands are annealed to form a protective four-way junction allowing …
Cellular feedback systems ensure genome maintenance during DNA replication. When replication forks stall, newly replicated DNA is protected by pathways that limit excessive …
Human development relies on the correct replication, maintenance and segregation of our genetic blueprints. How these processes are monitored across embryonic lineages, and why …

Summary The 53BP1-RIF1-shieldin pathway maintains genome stability by suppressing nucleolytic degradation of DNA ends at double-strand breaks (DSBs). Although RIF1 …

Nonhomologous end-joining (NHEJ) factors act in replication-fork protection, restart, and repair. Here, we identified a mechanism related to RNA: DNA hybrids to establish the NHEJ …
