SYCE2 is required for synaptonemal complex assembly, double strand break repair, and homologous recombination

Synapsis is the process by which paired chromosome homologues closely associate in meiosis before crossover. In the synaptonemal complex (SC), axial elements of each homologue connect through molecules of SYCP1 to the central element, which contains the proteins SYCE1 and -2. We have derived mice lacking SYCE2 protein, producing males and females in which meiotic chromosomes align and axes form...

Ctf18 is required for homologous recombination-mediated double-strand break repair

The efficient repair of double-strand breaks (DSBs) is crucial in maintaining genomic integrity. Sister chromatid cohesion is important for not only faithful chromosome segregation but also for proper DSB repair. During DSB repair, the Smc1-Smc3 cohesin complex is loaded onto chromatin around the DSB to support recombination-mediated DSB repair. In this study, we investigated whether Ctf18, a f...

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...

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...

DNA double-strand break repair in Penaeus monodon is predominantly dependent on homologous recombination

DNA double-strand breaks (DSBs) are mostly repaired by nonhomologous end joining (NHEJ) and homologous recombination (HR) in higher eukaryotes. In contrast, HR-mediated DSB repair is the major double-strand break repair pathway in lower order organisms such as bacteria and yeast. Penaeus monodon, commonly known as black tiger shrimp, is one of the economically important crustaceans facing large...
