DNA Double-Strand Break Repair
ownloade C regulates a myriad of genes controlling cell proliferation, metabolism, differentiation, and apoptosis. lso controls the expression of DNA double-strand break (DSB) repair genes and therefore may be a ial target for anticancer therapy to sensitize cancer cells to DNA damage or prevent genetic instability. report, we studied whether MYC binds to DSB repair gene promoters and modulates...
متن کاملDNA double-strand break repair
The integrity of genomic DNA is crucial for its function. And yet, DNA in living cells is inherently unstable. It is subject to mechanical stress and to many types of chemical modification that may lead to breaks in one or both strands of the double helix. Within the cell, reactive oxygen species generated by normal respiratory metabolism can cause double-strand breaks, as can stalled DNA repli...
متن کاملNbs1 Flexibly Tethers Ctp1 and Mre11-Rad50 to Coordinate DNA Double-Strand Break Processing and Repair
The Nijmegen breakage syndrome 1 (Nbs1) subunit of the Mre11-Rad50-Nbs1 (MRN) complex protects genome integrity by coordinating double-strand break (DSB) repair and checkpoint signaling through undefined interactions with ATM, MDC1, and Sae2/Ctp1/CtIP. Here, fission yeast and human Nbs1 structures defined by X-ray crystallography and small angle X-ray scattering (SAXS) reveal Nbs1 cardinal feat...
متن کاملTwo separable functions of Ctp1 in the early steps of meiotic DNA double-strand break repair
Meiotic programmed DNA double-strand break (DSB) repair is essential for crossing-over and viable gamete formation and requires removal of Spo11-oligonucleotide complexes from 5' ends (clipping) and their resection to generate invasive 3'-end single-stranded DNA (resection). Ctp1 (Com1, Sae2, CtIP homolog) acting with the Mre11-Rad50-Nbs1 (MRN) complex is required in both steps. We isolated mul...
متن کاملSilencing , Heterochromatin , and DNA Double Strand Break Repair in
The repair of damaged DNA is a crucial function carried out by all cells. Unrepaired DNA damage can lead to mutation, loss of genetic information, cellular transformation, or cell death. The DNA double strand break (DSB) is one type of damage that must be efficiently and accurately repaired. Two general mechanisms are employed by eukaryotic cells to repair DSBs: homologous recombination and non...
