    • Regulation of atypical MAP kinases ERK3 and ERK4 by the phosphatase DUSP2 

      Perander, Maria; Al-Mahdi, Rania; Jensen, Thomas Clemens; Nunn, Jennifer Ann Lillebo; Kildalsen, Hanne; Johansen, Bjarne Herold; Gabrielsen, Mads; Keyse, Stephen M; Seternes, Ole Morten (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-03-02)
      The atypical MAP kinases ERK3 and ERK4 are activated by phosphorylation of a serine residue lying within the activation loop signature sequence S-E-G. However, the regulation of ERK3 and ERK4 phosphorylation and activity is poorly understood. Here we report that the inducible nuclear dual-specificity MAP kinase phosphatase (MKP) DUSP2, a known regulator of the ERK and p38 MAPKs, is unique amongst ...
    • Regulation of Expression of Autophagy Genes by Atg8a-Interacting Partners Sequoia, YL-1, and Sir2 in Drosophila 

      Jacomin, Anne-Claire; Petridi, Stavroula; Di Monaco, Marisa; Bhujabal, Zambarlal; Jain, Ashish; Mulakkal, Nitha C.; Palara, Anthimi; Powell, Emma L.; Chung, Bonita; Zampronio, Cleidiane; Jones, Alexandra; Cameron, Alexander; Johansen, Terje; Nezis, Ioannis P. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-26)
      Autophagy is the degradation of cytoplasmic material through the lysosomal pathway. One of the most studied autophagy-related proteins is LC3. Despite growing evidence that LC3 is enriched in the nucleus, its nuclear role is poorly understood. Here, we show that <i>Drosophila</i> Atg8a protein, homologous to mammalian LC3, interacts with the transcription factor Sequoia in a LIR motif-dependent ...
    • Regulation of gap junction intercellular communication by connexin ubiquitination: physiological and pathophysiological implications 

      Totland, Max; Rasmussen, Nikoline Lander; Knudsen, Lars Mørland; Leithe, Edward (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-09-09)
      Gap junctions consist of arrays of intercellular channels that enable adjacent cells to communicate both electrically and metabolically. Gap junctions have a wide diversity of physiological functions, playing critical roles in both excitable and non-excitable tissues. Gap junction channels are formed by integral membrane proteins called connexins. Inherited or acquired alterations in connexins are ...
    • Regulation of Golgi turnover by CALCOCO1-mediated selective autophagy 

      Nthiga, Thaddaeus Mutugi; Shrestha, Birendra Kumar; Bruun, Jack-Ansgar; Larsen, Kenneth Bowitz; Lamark, Trond; Johansen, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-19)
      The Golgi complex is essential for the processing, sorting, and trafficking of newly synthesized proteins and lipids. Golgi turnover is regulated to meet different cellular physiological demands. The role of autophagy in the turnover of Golgi, however, has not been clarified. Here we show that CALCOCO1 binds the Golgi-resident palmitoyltransferase ZDHHC17 to facilitate Golgi degradation by autophagy ...
    • Regulation of Transcriptional Activity of Merkel Cell Polyomavirus Large T-Antigen by PKA-Mediated Phosphorylation 

      Falquet, Mar; Prezioso, Carla; Ludvigsen, Maria A.; Bruun, Jack-Ansgar; Passerini, Sara; Sveinbjørnsson, Baldur; Pietropaolo, Valeria; Moens, Ugo (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-01-03)
      Merkel cell polyomavirus (MCPyV) is the major cause of Merkel cell carcinoma (MCC), an aggressive skin cancer. MCPyV large T-antigen (LTag) and small T-antigen (sTag) are the main oncoproteins involved in MCPyV-induced MCC. A hallmark of MCPyV-positive MCC cells is the expression of a C-terminal truncated LTag. Protein kinase A (PKA) plays a fundamental role in a variety of biological processes, ...
