RecX facilitates homologous recombination by modulating RecA activities.
PLoS Genetics, 2012 The Bacillus subtilis recH342 strain, which decreases interspecies recombination without significantly affecting the frequency of transformation with homogamic DNA, carried a point mutation in the putative recX (yfhG) gene, and the mutation was renamed ...

Mismatch repair in recombination of bacteriophage T4
Biomolecular Concepts, 2012 The review focuses on the mechanism of mismatch repair in bacteriophage T4. It was first observed in T4 as an extra recombination mechanism, which contributed to the general recombination only when particular rII mutations were used as genetic markers ...

Structural basis for Rap1-Rif1-Rif2 assembly : insights into budding yeast telomere architecture and functions [PDF]
, 2012 Telomeres form the ends of eukaryotic linear chromosomes and are composed of specialized nucleoprotein complexes. They have been the subject of intense investigation over several decades, as telomere dysfunction has been associated with genome ...

PLoS ONE, 2011 Efficient repair of DNA double-stranded breaks (DSB) requires a coordinated response at the site of lesion. Nucleolytic resection commits repair towards homologous recombination, which preferentially occurs between sister chromatids.

, 2015 The nuclear pore complex (NPC) is emerging as a center for recruitment of a class of "difficult to repair" lesions such as double-strand breaks without a repair template and eroded telomeres in telomerase-deficient cells. In addition to such pathological

Meiotic double-strand break repair DNA synthesis tracts in Arabidopsis thaliana.
PLoS GeneticsWe report here the successful labelling of meiotic prophase I DNA synthesis in the flowering plant, Arabidopsis thaliana. Incorporation of the thymidine analogue, EdU, enables visualisation of the footprints of recombinational repair of programmed ...

Transcription-coupled nucleotide excision repair and its regulation by the DNA damage checkpoint
, 2009 Elaborate DNA repair mechanisms have evolved, allowing cells to repair damages in their genomes. Nucleotide excision repair (NER) removes a variety of helix-distorting lesions, including those caused by ultraviolet (UV) irradiation.
