    • ATG8 Family Proteins Act as Scaffolds for Assembly of the ULK Complex SEQUENCE REQUIREMENTS FOR LC3-INTERACTING REGION (LIR) MOTIFS 

      Alemu, Endalkachew Ashenafi; Lamark, Trond; Torgersen, Knut Martin; Birgisdottir, Åsa birna; Larsen, Kenneth Bowitz; Jain, Ashish; Olsvik, Hallvard Lauritz; Øvervatn, Aud Karin; Kirkin, Vladimir; Johansen, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2012-10-05)
      Autophagy is a lysosome-dependent degradation system conserved among eukaryotes. The mammalian Atg1 homologues, Unc-51 like kinase (ULK) 1 and 2, are multifunctional proteins with roles in autophagy, neurite outgrowth, and vesicle transport. The mammalian ULK complex involved in autophagy consists of ULK1, ULK2, ATG13, FIP200, and ATG101. We have used pulldown and peptide array overlay assays to ...

    • Autophagy and endocytosis – interconnections and interdependencies 

      Birgisdottir, Åsa birna; Johansen, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-22)
      Autophagy and endocytosis are membrane-vesicle-based cellular pathways for degradation and recycling of intracellular and extracellular components, respectively. These pathways have a common endpoint at the lysosome, where their cargo is degraded. In addition, the two pathways intersect at different stages during vesicle formation, fusion and trafficking, and share parts of the molecular machinery. ...

    • High-resolution visualization and assessment of basal and OXPHOS-induced mitophagy in H9c2 cardiomyoblasts 

      Godtliebsen, Gustav; Larsen, Kenneth Bowitz; Bhujabal, Zambarlal Babanrao; Opstad, Ida Sundvor; Nager Grifo, Mireia; Punnakkal, Abhinanda Ranjit; Kalstad, Trine; Olsen, Randi; Lund, trine; Prasad, Dilip K.; Agarwal, Krishna; Myrmel, Truls; Birgisdottir, Åsa birna (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-05)
      Mitochondria are susceptible to damage resulting from their activity as energy providers. Damaged mitochondria can cause harm to the cell and thus mitochondria are subjected to elaborate quality-control mechanisms including elimination via lysosomal degradation in a process termed mitophagy. Basal mitophagy is a house-keeping mechanism fine-tuning the number of mitochondria according to the metabolic ...

    • Use of Peptide Arrays for Identification and Characterization of LIR Motifs 

      Rasmussen, Mads Skytte; Birgisdottir, Åsa birna; Johansen, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-05)
      The mammalian ATG8 proteins (LC3A-C/GABARAP, GABARAPL1, and GABARAPL2) are small ubiquitin-like proteins critically involved in macroautophagy. Their processed C-termini are posttranslationally conjugated to a phosphatidylethanolamine moiety, enabling their insertion into the lipid bilayers of both the inner and outer membranes of the forming autophagosomes. The ATG8s bind a diverse selection of ...
