  1. Fasullo M, Dong Z, Sun M, Zeng L. Saccharomyces cerevisiae RAD53 (CHK2) but not CHK1 is required for double-strand break-initiated SCE and DNA damage-associated SCE after exposure to X rays and chemical agents. DNA Repair (Amst). 2005;4:1240-51 pubmed
    ..These data indicate that RAD53, not CHK1, is required for DSB-initiated SCE, and DNA damage-associated SCE after exposure to X-ray-mimetic and UV-mimetic chemicals. ..
  2. Fasullo M, Sun M. The Saccharomyces cerevisiae checkpoint genes RAD9, CHK1 and PDS1 are required for elevated homologous recombination in a mec1 (ATR) hypomorphic mutant. Cell Cycle. 2008;7:2418-26 pubmed
    ..We suggest that checkpoint genes that function in the RAD9-mediated pathway are required for either homologous recombination or DNA damage resistance in the S phase checkpoint mutant mec1-21. ..
  3. Fasullo M, Sun M. UV but not X rays stimulate homologous recombination between sister chromatids and homologs in a Saccharomyces cerevisiae mec1 (ATR) hypomorphic mutant. Mutat Res. 2008;648:73-81 pubmed publisher
    ..We suggest that although recombinational repair of double-stand breaks is less efficient in mec1 mutants, recombinants may be generated by other mechanisms, such as break-induced replication. ..
  4. Fasullo M, Tsaponina O, Sun M, Chabes A. Elevated dNTP levels suppress hyper-recombination in Saccharomyces cerevisiae S-phase checkpoint mutants. Nucleic Acids Res. 2010;38:1195-203 pubmed publisher
    ..We suggest that higher dNTP levels in specific checkpoint mutants suppress the formation of recombinogenic lesions. ..
