    • 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 ...

    • DOR/Tp53inp2 and Tp53inp1 Constitute a Metazoan Gene Family Encoding Dual Regulators of Autophagy and Transcription 

      Sancho, Ana; Duran, Jordi; Garcia-Espana, Antonio; Mauvezin, Caroline; Alemu, Endalkachew Ashenafi; Lamark, Trond; Macias, Maria J.; DeSalle, Rob; Royo, Miriam; Sala, David; Chicote, Javier U.; Palacin, Manuel; Johansen, Terje; Zorzano, Antonio (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Human DOR/TP53INP2 displays a unique bifunctional role as a modulator of autophagy and gene transcription. However, the domains or regions of DOR that participate in those functions have not been identified. Here we have performed structure/function analyses of DOR guided by identification of conserved regions in the DOR gene family by phylogenetic reconstructions. We show that DOR is present in ...

    • NIMA-related kinase 9–mediated phosphorylation of the microtubule-associated LC3B protein at Thr-50 suppresses selective autophagy of p62/sequestosome 1 

      Shrestha, Birendra Kumar; Rasmussen, Mads Skytte; Abudu, Yakubu Princely; Bruun, Jack-Ansgar; Larsen, Kenneth Bowitz; Alemu, Endalkachew Ashenafi; Sjøttem, Eva; Lamark, Trond; Johansen, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-19)
      Human ATG8 family proteins (ATG8s) are active in all steps of the macroautophagy pathway, and their lipidation is essential for autophagosome formation. Lipidated ATG8s anchored to the outer surface of the phagophore serve as scaffolds for binding of other core autophagy proteins and various effector proteins involved in trafficking or fusion events, whereas those at the inner surface are needed for ...
