    • Co-translational, post-translational, and non-catalytic roles of N-terminal acetyltransferases 

      Aksnes, Henriette; Ree, Rasmus Moen; Arnesen, Thomas (Peer reviewed; Journal article, 2019)
      Recent studies of N-terminal acetylation have identified new N-terminal acetyltransferases (NATs) and expanded the known functions of these enzymes beyond their roles as ribosome-associated co-translational modifiers. For ...
    • Efficient and crucial quality control of HAP1 cell ploidy status 

      Beigl, Tobias B.; Kjosås, Ine; Seljeseth, Emilie; Glomnes, Nina; Aksnes, Henriette (Journal article; Peer reviewed, 2020)
      The near-haploid human cell line HAP1 recently became a popular subject for CRISPR/Cas9 editing, since only one allele requires modification. Through the gene-editing service at Horizon Discovery, there are at present more ...
    • Expanded in vivo substrate profile of the yeast N-terminal acetyltransferase NatC 

      Van Damme, Petra; Osberg, Camilla; Jonckheere, Veronique; Glomnes, Nina; Gevaert, Kris; Arnesen, Thomas; Aksnes, Henriette (Journal article; Peer reviewed, 2022)
      N-terminal acetylation is a conserved protein modification among eukaryotes. The yeast Saccharomyces cerevisiae is a valuable model system for studying this modification. The bulk of protein N-terminal acetylation in S. ...
    • Exploiting the potential of commercial digital holographic microscopy by combining it with 3D matrix cell culture assays 

      Hellesvik, Monica; Øye, Hanne; Aksnes, Henriette (Journal article; Peer reviewed, 2020)
      3D cell culture assays are becoming increasingly popular due to their higher resemblance to tissue environment. These provide an increased complexity compared to the growth on 2D surface and therefore allow studies of ...
    • First Things First: Vital Protein Marks by N-Terminal Acetyltransferases 

      Aksnes, Henriette; Drazic, Adrian; Marie, Michael Bruno Eric; Arnesen, Thomas (Peer reviewed; Journal article, 2016-09)
      N-terminal (Nt) acetylation is known to be a highly abundant co-translational protein modification, but the recent discovery of Golgi- and chloroplast-resident N-terminal acetyltransferases (NATs) revealed that it can also ...
