Relative contribution of four nucleases, CtIP, Dna2, Exo1 and Mre11, to the initial step of DNA double‐strand break repair by homologous recombination in both the chicken DT40 and human TK6 cell lines
2 Nov 2015
Abstract excerpt
Homologous recombination (HR) is initiated by double-strand break (DSB) resection, during which DSBs are processed by nucleases to generate 3' single-strand DNA. DSB resection is initiated by CtIP and Mre11 followed by long-range resection by Dna2 and Exo1 in Saccharomyces cerevisiae. To analyze the relative contribution of four nucleases, CtIP, Mre11, Dna2 and Exo1, to DSB resection, we disrupted genes encoding...
