From GEO summary: To segregate accurately during meiosis, homologous chromosomes in most species must recombine. Very small chromosomes would risk missegregation if recombination were randomly distributed, so the double-strand breaks (DSBs) that initiate recombination are not haphazard. How this nonrandomness is controlled is not understood. Here we demonstrate that Saccharomyces cerevisiae integrates...

From GEO summary: Genome binding/occupancy profiling by high throughput sequencing. Meiotic recombination starts with the formation of DNA double-strand breaks (DSBs) made by Spo11. In Saccharomyces cerevisiae, the nonrandom distribution of meiotic DSBs along the genome can be attributed to the combined influence of multiple factors on Spo11 cleavage. One factor is higher-order chromatin structure,...

From GEO summary: Genome binding/occupancy profiling by high throughput sequencing. DNA duplication is intimately connected to setting up post-replicative chromosome structures and events, but molecular details of this coordination are not well understood. A striking example occurs during yeast meiosis, where replication locally influences timing of the DNA double-strand breaks (DSBs) that initiate...

Description from Proteome Xchange: "Mlh3 internally tagged with Flag was pulled down from synchronous meiotic cells at t = 4 h in meiosis, in order to identify its interacting partners involved in meiotic crossover formation" Sample Processing Protocol from PRIDE: "2.1010 cells of VBD1674 strain at 4 h in meiosis were harvested, washed two times with ice-cold TNG buffer (50 mM Tris/HCl pH 8; 150...

Summary from the GEO: "Programmed DNA double-strand breaks (DSBs) initiate meiotic recombination and their subsequent repair culminates in crossover (CO) formation. COs result from the asymmetric cleavage of double-Holliday junction (dHJ) intermediates, that requires the MutLγ complex together with a non-catalytic function of Exo1, an activity essential for fertility but at risk of generating unwanted...

Description from the ProteomeXchange: "Exo1 tagged with the TAP sequence was pulled down from synchronous ndt80∆ meiotic cells after induction of the CDC5 kinase at t = 8 h 15 in meiosis (1 h 15 after CDC5 induction), in order to identify its phosphorylated residues" PRIDE Sample Processing Protocol: "2.1010 cells of VBD2070 strain were harvested after 8 h 15 min in sporulation medium and processed...

Summary from the GEO: "Abstract: Quality control requires discrimination between functional and aberrant species to selectively target substrates for destruction. Nuclear RNA quality control in Saccharomyces cerevisiae includes the TRAMP complex that marks RNA for decay via polyadenylation and helicase-dependent 3′ to 5′ degradation by the RNA exosome. Using reconstitution biochemistry we show that...

Summary from the GEO: "Saccharomyces cerevisiae Mek1 is a CHK2/Rad53-family kinase that regulates meiotic recombination and progression upon its activation in response to DNA double-strand breaks (DSBs). The full catalog of direct Mek1 phosphorylation targets remains unknown. Here, we show that phosphorylation of histone H3 on threonine 11 (H3 T11ph) is induced by meiotic DSBs in S. cerevisiae and...
