    • 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 ...

    • The FMRpolyGlycine protein mediates aggregate formation and toxicity independent of the CGG mRNA hairpin in a cellular model for FXTAS 

      Hoem, Gry; Larsen, Kenneth Bowitz; Øvervatn, Aud Karin; Brech, Andreas; Lamark, Trond; Sjøttem, Eva; Johansen, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-28)
      Fragile X-associated tremor/ataxia syndrome (FXTAS) is a neurodegenerative disorder caused by a CGG-repeat expansion in the 5′ UTR of the FMR1 gene on the X-chromosome. Both elevated levels of the expanded FMR1 mRNA and aberrant expression of a polyglycine protein (FMRpolyG) from the CGG-repeat region are hypothesized to trigger the pathogenesis of FXTAS. While increased expression of FMRpolyG leads ...

    • FYCO1 contains a C-terminally extended, LC3A/B-preferring LC3-interacting region (LIR) motif required for efficient maturation of autophagosomes during basal autophagy 

      Olsvik, Hallvard Lauritz; Lamark, Trond; Takagi, Kenji; Larsen, Kenneth Bowitz; Evjen, gry; Øvervatn, Aud Karin; Mizushima, Tsunehiro; Johansen, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-10-14)
      FYCO1 (FYVE and coiled-coil protein 1) is a transport adaptor that binds to phosphatidylinositol 3-phosphate, to Rab7, and to LC3 (microtubule-associated protein 1 light chain 3) to mediate transport of late endosomes and autophagosomes along microtubules in the plus end direction. We have previously shown that FYCO1 binds to LC3B via a 19-amino acid sequence containing a putative core LC3-interacting ...
