Sgs1 and Mph1 Helicases Enforce the Recombination Execution Checkpoint During DNA Double-Strand Break Repair in Saccharomyces cerevisiae.
We have previously shown that a recombination execution checkpoint (REC) regulates the choice of the homologous recombination pathway used to repair a given DNA double-strand break (DSB) based on the homology status of the DSB ends. If the two DSB ends are synapsed with closely-positioned and correctly-oriented homologous donors, repair proceeds rapidly by the gene conversion (GC) pathway. If, ...
متن کاملTbf1 and Vid22 promote resection and non-homologous end joining of DNA double-strand break ends.
The repair of DNA double-strand breaks (DSBs) is crucial for maintaining genome stability. The Saccharomyces cerevisiae protein Tbf1, which is characterized by a Myb domain and is related to mammalian TRF1 and TRF2, has been proposed to act as a transcriptional activator. Here, we show that Tbf1 and its interacting protein Vid22 are new players in the response to DSBs. Inactivation of either TB...
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 کاملCtIP links DNA double-strand break sensing to resection.
In response to DNA double-strand breaks (DSBs), cells sense the DNA lesions and then activate the protein kinase ATM. Subsequent DSB resection produces RPA-coated ssDNA that is essential for activation of the DNA damage checkpoint and DNA repair by homologous recombination (HR). However, the biochemical mechanism underlying the transition from DSB sensing to resection remains unclear. Using Xen...

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...
