    Description: Double-strand breaks (DSBs) in Saccharomyces cerevisiae can be repaired by gene conversions or by deletions resulting from single-strand annealing between direct repeats of homologous sequences. Although rad1 mutants are resistant to x-rays and can complete DSB-mediated mating-type switching, they could not complete recombination when the ends of the break contained approximately 60 base pairs of nonhomology. Recombination was restored when the ends of the break were made homologous to donor sequences. Additionally, the absence of RAD1 led to the frequent appearance of a previously unobserved type of recombination product. These data suggest RAD1 is required to remove nonhomologous DNA from the 3' ends of recombining DNA, a process analogous to the excision of photodimers during repair of ultraviolet-damaged DNA.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fishman-Lobell, J -- Haber, J E -- GM01722/GM/NIGMS NIH HHS/ -- GM20056/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1992 Oct 16;258(5081):480-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Rosenstiel Basic Medical Sciences Research Center, Brandeis University, Waltham, MA 02254.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1411547" target="_blank"〉PubMed〈/a〉

    Description: Armakolas and Klar (Reports, 24 February 2006, p. 1146) suggested that segregation of mouse chromosome 7, after induction of a site-specific crossover between homologous chromosomes, is driven by a preferential inheritance of the old Watson and the old Crick DNA strands. However, this interpretation only considered half of the possible outcomes. The conjecture fails when all possible outcomes are examined.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Haber, James E -- New York, N.Y. -- Science. 2006 Aug 25;313(5790):1045; author reply 1045.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Rosenstiel Center and Department of Biology, Brandeis University, Waltham, MA 02454-9110, USA. haber@brandeis.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16931739" target="_blank"〉PubMed〈/a〉

    Description: The repair of chromosomal double strand breaks (DSBs) is crucial for the maintenance of genomic integrity. However, the repair of DSBs can also destabilize the genome by causing mutations and chromosomal rearrangements, the driving forces for carcinogenesis and hereditary diseases. Break-induced replication (BIR) is one of the DSB repair pathways that is highly prone to genetic instability. BIR proceeds by invasion of one broken end into a homologous DNA sequence followed by replication that can copy hundreds of kilobases of DNA from a donor molecule all the way through its telomere. The resulting repaired chromosome comes at a great cost to the cell, as BIR promotes mutagenesis, loss of heterozygosity, translocations, and copy number variations, all hallmarks of carcinogenesis. BIR uses most known replication proteins to copy large portions of DNA, similar to S-phase replication. It has therefore been suggested that BIR proceeds by semiconservative replication; however, the model of a bona fide, stable replication fork contradicts the known instabilities associated with BIR such as a 1,000-fold increase in mutation rate compared to normal replication. Here we demonstrate that in budding yeast the mechanism of replication during BIR is significantly different from S-phase replication, as it proceeds via an unusual bubble-like replication fork that results in conservative inheritance of the new genetic material. We provide evidence that this atypical mode of DNA replication, dependent on Pif1 helicase, is responsible for the marked increase in BIR-associated mutations. We propose that the BIR mode of synthesis presents a powerful mechanism that can initiate bursts of genetic instability in eukaryotes, including humans.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3804423/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3804423/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Saini, Natalie -- Ramakrishnan, Sreejith -- Elango, Rajula -- Ayyar, Sandeep -- Zhang, Yu -- Deem, Angela -- Ira, Grzegorz -- Haber, James E -- Lobachev, Kirill S -- Malkova, Anna -- GM080600/GM/NIGMS NIH HHS/ -- GM76020/GM/NIGMS NIH HHS/ -- R01 GM080600/GM/NIGMS NIH HHS/ -- R01GM082950/GM/NIGMS NIH HHS/ -- R01GM084242/GM/NIGMS NIH HHS/ -- R03 ES016434/ES/NIEHS NIH HHS/ -- R03ES016434/ES/NIEHS NIH HHS/ -- R37 GM020056/GM/NIGMS NIH HHS/ -- England -- Nature. 2013 Oct 17;502(7471):389-92. doi: 10.1038/nature12584.

    Description: Cellular checkpoints prevent mitosis in the presence of stalled replication forks. Whether checkpoints also ensure the completion of DNA replication before mitosis is unknown. Here, we show that in yeast smc5-smc6 mutants, which are related to cohesin and condensin, replication is delayed, most significantly at natural replication-impeding loci like the ribosomal DNA gene cluster. In the absence of Smc5-Smc6, chromosome nondisjunction occurs as a consequence of mitotic entry with unfinished replication despite intact checkpoint responses. Eliminating processes that obstruct replication fork progression restores the temporal uncoupling between replication and segregation in smc5-smc6 mutants. We propose that the completion of replication is not under the surveillance of known checkpoints.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Torres-Rosell, Jordi -- De Piccoli, Giacomo -- Cordon-Preciado, Violeta -- Farmer, Sarah -- Jarmuz, Adam -- Machin, Felix -- Pasero, Philippe -- Lisby, Michael -- Haber, James E -- Aragon, Luis -- GM 20056/GM/NIGMS NIH HHS/ -- MC_U120074328/Medical Research Council/United Kingdom -- R01 GM061766/GM/NIGMS NIH HHS/ -- R01 GM061766-07/GM/NIGMS NIH HHS/ -- R01 GM061766-08/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2007 Mar 9;315(5817):1411-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cell Cycle Group, Medical Research Council (MRC) Clinical Sciences Centre, Faculty of Medicine, Imperial College London, Hammersmith Hospital Campus, Du Cane Road, London W12 0NN, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17347440" target="_blank"〉PubMed〈/a〉

    Description: To examine the fidelity of DNA synthesis during double-strand break (DSB) repair in Saccharomyces cerevisiae we studied gene conversion in which both strands of DNA are newly synthesized. The mutation rate increases up to 1400 times over spontaneous events, with a significantly different mutation signature. Especially prominent are microhomology-mediated template switches. Recombination-induced mutations are largely independent of mismatch repair, by DNA polymerases Polzeta, Poleta, and Pol32, but result from errors made by Poldelta and Polepsilon. These observations suggest that increased DSB frequencies in oncogene-activated mammalian cells may also increase the probability of acquiring mutations required for transition to a cancerous state.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4254764/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4254764/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hicks, Wade M -- Kim, Minlee -- Haber, James E -- GM007122/GM/NIGMS NIH HHS/ -- GM20056/GM/NIGMS NIH HHS/ -- R01 GM020056/GM/NIGMS NIH HHS/ -- R37 GM020056/GM/NIGMS NIH HHS/ -- T32 GM007122/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2010 Jul 2;329(5987):82-5. doi: 10.1126/science.1191125.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology and Rosenstiel Center, Brandeis University, Waltham, MA 02454-9110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20595613" target="_blank"〉PubMed〈/a〉

    Description: In budding yeast, one-ended DNA double-strand breaks (DSBs) and damaged replication forks are repaired by break-induced replication (BIR), a homologous recombination pathway that requires the Pol32 subunit of DNA polymerase delta. DNA replication stress is prevalent in cancer, but BIR has not been characterized in mammals. In a cyclin E overexpression model of DNA replication stress, POLD3, the human ortholog of POL32, was required for cell cycle progression and processive DNA synthesis. Segmental genomic duplications induced by cyclin E overexpression were also dependent on POLD3, as were BIR-mediated recombination events captured with a specialized DSB repair assay. We propose that BIR repairs damaged replication forks in mammals, accounting for the high frequency of genomic duplications in human cancers.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4047655/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4047655/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Costantino, Lorenzo -- Sotiriou, Sotirios K -- Rantala, Juha K -- Magin, Simon -- Mladenov, Emil -- Helleday, Thomas -- Haber, James E -- Iliakis, George -- Kallioniemi, Olli P -- Halazonetis, Thanos D -- R01 GM076020/GM/NIGMS NIH HHS/ -- R37 GM020056/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2014 Jan 3;343(6166):88-91. doi: 10.1126/science.1243211.

    Description: A mutant allele of the chromosomal locus corresponding to the cloned actin gene of the yeast Saccharomyces cerevisiae has been constructed by DNA transformation with a hybrid plasmid which integrates into, and thereby disrupts, the protein-encoding sequences of the gene. In a diploid strain of yeast, disruption of the actin gene on one chromosome results in a mutation that segregates as a recessive lethal tightly linked to a selectable genetic marker on the integrated plasmid. The actin gene, therefore, must encode an essential function for yeast cell growth.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Shortle, D -- Haber, J E -- Botstein, D -- GM18973/GM/NIGMS NIH HHS/ -- GM20056/GM/NIGMS NIH HHS/ -- GM21253/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1982 Jul 23;217(4557):371-3.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7046050" target="_blank"〉PubMed〈/a〉

    Description: Although meiotic gene conversion has long been known to be accompanied by crossing-over, a direct test of the converse has not been possible. An experiment was designed to determine whether crossing-over is accompanied by gene conversion in Saccharomyces cerevisiae. Nine restriction site heterologies were introduced into a 9-kilobase chromosomal interval that exhibits 22 percent crossing-over. Of all the exchange events that occurred, at least 59 percent of meiotic crossovers are accompanied by gene conversion of one or more of the restriction site heterologies. The average gene conversion tract length was 1.5 kilobases. An unexpected result was that the introduction of as few as seven heterozygosities significantly altered the outcome of recombination events, reducing the frequency of crossovers by 50 percent and increasing the number of exceptional tetrads. This alteration results from a second recombination event induced by repair of heteroduplex DNA containing multiple mismatched base pairs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Borts, R H -- Haber, J E -- GM29736/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1987 Sep 18;237(4821):1459-65.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2820060" target="_blank"〉PubMed〈/a〉
