Double-strand break repair and homologous recombination in Schizosaccharomyces pombe.
The study of double-strand break repair and homologous recombination in Saccharomyces cerevisiae meiosis has provided important information about the mechanisms involved. However, it has become clear that the resulting recombination models are only partially applicable to repair in mitotic cells, where crossover formation is suppressed. In recent years our understanding of double-strand break r...
متن کاملSnapShot: 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 کاملReal-time analysis of double-strand DNA break repair by homologous recombination.
The ability to induce synchronously a single site-specific double-strand break (DSB) in a budding yeast chromosome has made it possible to monitor the kinetics and genetic requirements of many molecular steps during DSB repair. Special attention has been paid to the switching of mating-type genes in Saccharomyces cerevisiae, a process initiated by the HO endonuclease by cleaving the MAT locus. ...
متن کاملGenetic requirements for the single-strand annealing pathway of double-strand break repair in Saccharomyces cerevisiae.
HO endonuclease-induced double-strand breaks (DSBs) within a direct duplication of Escherichia coli lacZ genes are repaired either by gene conversion or by single-strand annealing (SSA), with > 80% being SSA. Previously it was demonstrated that the RAD52 gene is required for DSB-induced SSA. In the present study, the effects of other genes belonging to the RAD52 epistasis group were analyzed. W...
متن کاملCTCF facilitates DNA double-strand break repair by enhancing homologous recombination repair
The repair of DNA double-strand breaks (DSBs) is mediated via two major pathways, nonhomologous end joining (NHEJ) and homologous recombination (HR) repair. DSB repair is vital for cell survival, genome stability, and tumor suppression. In contrast to NHEJ, HR relies on extensive homology and templated DNA synthesis to restore the sequence surrounding the break site. We report a new role for th...
