    • Recessive Truncating Mutations in ALKBH8 Cause Intellectual Disability and Severe Impairment of Wobble Uridine Modification 

      Vågbø, Cathrine Broberg; Monies, Dorota; Al-Owain, Mohammad; Alhomaidi, Suzan; Alkuraya, Fowzan S. (Journal article; Peer reviewed, 2019)
      The wobble hypothesis was proposed to explain the presence of fewer tRNAs than possible codons. The wobble nucleoside position in the anticodon stem-loop undergoes a number of modifications that help maintain the efficiency ...

    • RNA in DNA repair 

      Vågbø, Cathrine Broberg; Slupphaug, Geir (Peer reviewed; Journal article, 2020)
      Our genome is constantly subject to damage from exogenous and endogenous sources, and cells respond to such damage by initiating a DNA damage response (DDR). Failure to induce an adequate DDR can result in increased mutation ...

    • Roles of Trm9-and ALKBH8-like proteins in the formation of modified wobble uridines in Arabidopsis tRNA 

      Leihne, VIbeke; Kirpekar, F; Vågbø, Cathrine Broberg; Van den Born, Erwin; Krokan, Hans Einar; Grini, Paul Eivind; Meza, Trine Johansen; Falnes, Pål (Journal article; Peer reviewed, 2011)
      Uridine at the wobble position of tRNA is usually modified, and modification is required for accurate and efficient protein translation. In eukaryotes, wobble uridines are modified into 5-methoxycarbonylmethyluridine (mcm ...

    • RPA guides UNG to uracil in ssDNA to facilitate antibody class switching and repair of mutagenic uracil at the replication fork 

      Hayran , Abdul Baset ; Liabakk, Nina-Beate; Aas, Per Arne; Kusnierczyk, Anna; Vågbø, Cathrine Broberg; Sarno, Antonio; Iveland, Tobias Solli; Chawla, Konika; Zahn, Astrid; DiNoia, Javier M; Slupphaug, Geir; Kavli, Bodil Merete (Peer reviewed; Journal article, 2023)
      Activation-induced cytidine deaminase (AID) interacts with replication protein A (RPA), the major ssDNA-binding protein, to promote deamination of cytosine to uracil in transcribed immunoglobulin (Ig) genes. Uracil-DNA ...

    • Splice site m<sup>6</sup>A methylation prevents binding of U2AF35 to inhibit RNA splicing 

      Mendel, Mateusz; Delaney, Kamila; Pandey, Radha Raman; Chen, Kuan-Ming; Wenda, Joanna M.; Vågbø, Cathrine Broberg; Steiner, Florian A.; Homolka, David; Pillai, Ramesh S. (Journal article; Peer reviewed, 2021)
      The N6-methyladenosine (m6A) RNA modification is used widely to alter the fate of mRNAs. Here we demonstrate that the C. elegans writer METT-10 (the ortholog of mouse METTL16) deposits an m6A mark on the 3′ splice site ...

    • Synergistic Actions of Ogg1 and Mutyh DNA Glycosylases Modulate Anxiety-like Behavior in Mice 

      Bjørge, Monica Dahl; Hildrestrand, Gunn Annette; Scheffler, Katja; Suganthan, Rajikala; Rolseth, Veslemøy; Kusnierczyk, Anna; Rowe, Alexander D.; Vågbø, Cathrine Broberg; Vetlesen, Susanne; Eide, Lars; Slupphaug, Geir; Yusaku, Nakabeppu; Timothy, Bredy; Klungland, Arne; Bjørås, Magnar (Journal article; Peer reviewed, 2015)
      Ogg1 and Mutyh DNA glycosylases cooperate to prevent mutations caused by 8-oxoG, a major premutagenic DNA lesion associated with cognitive decline. We have examined behavior and cognitive function in mice deficient of these ...

    • The DNA dioxygenase ALKBH2 protects Arabidopsis thaliana against methylation damage 

      Meza, Trine Johansen; Moen, Marivi; Vågbø, Cathrine Broberg; Krokan, Hans Einar; Klungland, Arne; Grini, Paul Eivind; Falnes, Pål (Journal article; Peer reviewed, 2012)
      The Escherichia coli AlkB protein (EcAlkB) is a DNA repair enzyme which reverses methylation damage such as 1-methyladenine (1-meA) and 3-methylcytosine (3-meC). The mammalian AlkB homologues ALKBH2 and ALKBH3 display ...

    • The human methyltransferase ZCCHC4 catalyses N6-methyladenosine modification of 28S ribosomal RNA 

      Pinto, Rita; Vågbø, Cathrine Broberg; Jakobsson, Magnus; Yeji, Kim; Baltissen, Marijke P; O'Donohue, Marie-Francoise; Guzman, Ulises H; Malecki, Jedrzej Mieczyslaw; Wu, Jie; Kirpekar, Finn; Olsen, Jesper V; Gleizes, Pierre-Emmanuel; Vermeulen, Michiel; Leidel, Sebastian A.; Slupphaug, Geir; Falnes, Pål Øystein (Journal article; Peer reviewed, 2019)
      RNA methylations are essential both for RNA structure and function, and are introduced by a number of distinct methyltransferases (MTases). In recent years, N6-methyladenosine (m6A) modification of eukaryotic mRNA has been ...

    • UNG-initiated base excision repair is the major repair route for 5-fluorouracil in DNA, but 5-fluorouracil cytotoxicity depends mainly on RNA incorporation 

      Pettersen, Henrik Sahlin; Visnes, Torkild; Vågbø, Cathrine Broberg; Svaasand, Eva K; Doseth, Berit; Slupphaug, Geir; Kavli, Bodil Merete; Krokan, Hans Einar (Journal article; Peer reviewed, 2011)
      Cytotoxicity of 5-fluorouracil (FU) and 5-fluoro-2′-deoxyuridine (FdUrd) due to DNA fragmentation during DNA repair has been proposed as an alternative to effects from thymidylate synthase (TS) inhibition or RNA incorporation. ...
