    • P62/sequestosome-1, autophagy-related gene 8, and autophagy in Drosophila are regulated by nuclear factor erythroid 2-related factor 2(NRF2), independent of transcription factor TFEB 

      Jain, Ashish; Rusten, Tor Erik; Katheder, Nadja Sandra; Elvenes, Julianne; Bruun, Jack-Ansgar; Sjøttem, Eva; Lamark, Trond; Johansen, Terje (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-04-30)
      The selective autophagy receptor p62/sequestosome 1 (SQSTM1) interacts directly with LC3 and is involved in oxidative stress signaling in two ways in mammals. First, p62 is transcriptionally induced upon oxidative stress by the NF-E2-related factor 2 (NRF2) by direct binding to an antioxidant response element in the p62 promoter. Second, p62 accumulation, occurring when autophagy is impaired, leads ...

    • Phosphorylation of Syntaxin 17 by TBK1 Controls Autophagy Initiation 

      Kumar, Suresh; Gu, Yuexi; Abudu, Yakubu Princely; Bruun, Jack-Ansgar; Jain, Ashish; Farzam, Farzin; Mudd, Michal H.; Anonsen, Jan Haug; Rusten, Tor Erik; Kasof, Gary; Ktistakis, Nicholas; Lidke, Keith A; Johansen, Terje; Deretic, Vojo (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-02-28)
      Syntaxin 17 (Stx17) has been implicated in autophagosome-lysosome fusion. Here, we report that Stx17 functions in assembly of protein complexes during autophagy initiation. Stx17 is phosphorylated by TBK1 whereby phospho-Stx17 controls the formation of the ATG13<sup>+</sup>FIP200<sup>+</sup> mammalian pre-autophagosomal structure (mPAS) in response to induction of autophagy. TBK1 phosphorylates Stx17 ...
