  1. pmc Homologous recombination and its regulation
    Lumir Krejci
    Department of Biology, Masaryk University, Brno, Czech Republic
    Nucleic Acids Res 40:5795-818. 2012

  2. pmc Srs2 mediates PCNA-SUMO-dependent inhibition of DNA repair synthesis
    Peter Burkovics
    National Centre for Biomolecular Research, Masaryk University, Brno, Czech Republic
    EMBO J 32:742-55. 2013
    ..Our results suggest that cycling cells use the Siz1-dependent SUMOylation of PCNA to limit the extension of repair synthesis during template switch or HR and attenuate reciprocal DNA strand exchanges to maintain genome stability...
  3. pmc Strand invasion by HLTF as a mechanism for template switch in fork rescue
    Peter Burkovics
    Institute of Genetics, Biological Research Center, Hungarian Academy of Sciences, HU 6726 Szeged, Hungary, Department of Biology, Masaryk University, Brno, Czech Republic, National Centre for Biomolecular Research, Masaryk University, Brno, Czech Republic and International Clinical Research Center, Center for Biomolecular and Cellular Engineering, St Anne s University Hospital Brno, CZ 62500 Brno, Czech Republic
    Nucleic Acids Res 42:1711-20. 2014
    ..Our data indicate that HLTF is involved in a RAD51-independent D-loop branch of template switch pathway that can promote repair of gaps formed during replication of damaged DNA. ..

    Marek Sebesta
    National Centre for Biomolecular Research, Masaryk University, Brno, Czech Republic
    DNA Repair (Amst) 12:691-8. 2013
    ..In addition, the presence of PCNA on the D-loop regulates the length of the extension tracks by recruiting various polymerases and might present a regulatory point for the various recombination outcomes. ..
