      Purpose: Reactive oxygen species (ROS) are an important part of the inflammatory response during infection but can also promote DNA damage. Due to the sustained inflammation in severe Covid-19, we hypothesized that ...
    • RPA2 winged-helix domain facilitates UNG-mediated removal of uracil from ssDNA; implications for repair of mutagenic uracil at the replication fork 

      Kavli, Bodil Merete; Iveland, Tobias Solli; Buchinger, Edith; Hagen, Lars; Liabakk, Nina-Beate; Aas, Per Arne; Obermann, Tobias Sebastian; Aachmann, Finn Lillelund; Slupphaug, Geir (Journal article; Peer reviewed, 2021)
      Uracil occurs at replication forks via misincorporation of deoxyuridine monophosphate (dUMP) or via deamination of existing cytosines, which occurs 2-3 orders of magnitude faster in ssDNA than in dsDNA and is 100% miscoding. ...
