  1. ...meiotic recombination. PRDM9 binds DNA at particular sequence motifs (#1), a subset of which become sites of programmed DSBs by SPO11 (#2). Strand resection creates ssDNA overhangs, which are bound by RPA first (#3) and then by DMC1 and RAD51 (#4). Binding occurs to the left of the break on the forward...
  2. ...immunoprecipitation followed by sequencing (SPI-seq) to map genomic hotspots of DNA damage. We demonstrated this method with Rad52, a homologous recombination repair protein, which binds to ssDNA formed at DNA lesions. SPI-seq faithfully detected, in fission yeast, Rad52 enrichment at artificially induced double...
  3. .... Numerical constraints and feedback control of double-strand breaks in mouse meiosis. Genes Dev 27: 873–886. doi:10.1101/gad.213652.113 ↵Khil PP, Smagulova F, Brick KM, Camerini-Otero RD, Petukhova GV. 2012. Sensitive mapping of recombination hotspots using sequencing-based detection of ssDNA. Genome Res 22...
  4. ...:T-to-G:C substitutions. This effect has been detected at mouse recombination hotspots, defined by DMC1 ChIP-seq (Clement and Arndt 2013). GC-biased gene conversion can be measured by estimating the GC content at equilibrium, also named GC∗ (see Methods). At class 1 sites, a sharp GC∗ increase was detected at the center...
  5. ...taxonomic classes, including dsDNA, ssDNA, dsRNA, ssRNA (−), ssRNA (+), and retroviruses (Fig. 1B). This library incorporates all currently characterized viral s and represents the largest existing viral reference library.View larger version: In this window In a new window Figure 1. Discovering oncovirus...
  6. ...interhomolog DSB repair by homologous recombination may be unfavorable. Instead, the 39 ssDNA tail can seek out its annealing partner by taking advantage of the first few nucleotides, which mediate formation of transient secondary structures by ‘‘loopingout’’ or ‘‘snapping-back’’ motions and prime strand...
