SnapShot: Homologous Recombination in DNA Double-Strand Break Repair
Homologous recombination (HR) provides an important mechanism to repair both accidental and programmed DNA double-strand breaks (DSBs) during mitosis and meiosis. Defects in HR are associated with mutagenesis and predispose to cancer, highlighting the importance of this pathway for preserving genome integrity (Moynahan and Jasin, 2010). HR is active in the S and G2 phases of the cell cycle wher...
متن کاملHomologous and non-homologous recombination differentially affect DNA damage repair in mice.
Ionizing radiation and interstrand DNA crosslinking compounds provide important treatments against cancer due to their extreme genotoxicity for proliferating cells. Both the efficacies of such treatments and the mutagenic potential of these agents are modulated by the ability of cells to repair the inflicted DNA damage. Here we demonstrate that homologous recombination-deficient mRAD54(-/-) mic...
متن کاملDEK is required for homologous recombination repair of DNA breaks
DEK is a highly conserved chromatin-bound protein whose upregulation across cancer types correlates with genotoxic therapy resistance. Loss of DEK induces genome instability and sensitizes cells to DNA double strand breaks (DSBs), suggesting defects in DNA repair. While these DEK-deficiency phenotypes were thought to arise from a moderate attenuation of non-homologous end joining (NHEJ) repair,...
متن کاملRAD18 transmits DNA damage signalling to elicit homologous recombination repair
To maintain genome stability, cells respond to DNA damage by activating signalling pathways that govern cell-cycle checkpoints and initiate DNA repair. Cell-cycle checkpoint controls should connect with DNA repair processes, however, exactly how such coordination occurs in vivo is largely unknown. Here we describe a new role for the E3 ligase RAD18 as the integral component in translating the d...
متن کاملResolvase OsGEN1 Mediates DNA Repair by Homologous Recombination.
Yen1/GEN1 are canonical Holliday junction resolvases that belong to the RAD2/XPG family. In eukaryotes, such as budding yeast, mice, worms, and humans, Yen1/GEN1 work together with Mus81-Mms4/MUS81-EME1 and Slx1-Slx4/SLX1-SLX4 in DNA repair by homologous recombination to maintain genome stability. In plants, the biological function of Yen1/GEN1 remains largely unclear. In this study, we charact...
