    • The Selective Autophagy Receptor p62 Forms a Flexible Filamentous Helical Scaffold 

      Ciuffa, Rodolfo; Lamark, Trond; Tarafder, Abul K.; Guesdon, Audrey; Rybina, Sofia; Hagen, Wim J.H.; Johansen, Terje; Sachse, Carsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-05-05)
      The scaffold protein p62/SQSTM1 is involved in protein turnover and signaling and is commonly found in dense protein bodies in eukaryotic cells. In autophagy, p62 acts as a selective autophagy receptor that recognizes and shuttles ubiquitinated proteins to the autophagosome for degradation. The structural organization of p62 in cellular bodies and the interplay of these assemblies with ubiquitin ...

    • Structural basis of p62/SQSTM1 helical filaments and their role in cellular cargo uptake 

      Jakobi, Arjen J.; Huber, Stefan T.; Mortensen, Simon A.; Schultz, Sebastian; Palara, Anthimi; Kuhm, Tanja; Shrestha, Birendra Kumar; Lamark, Trond; Hagen, Wim J.H.; Wilmanns, Matthias; Johansen, Terje; Brech, Andreas; Sachse, Carsten (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-23)
      p62/SQSTM1 is an autophagy receptor and signaling adaptor with an N-terminal PB1 domain that forms the scaffold of phase-separated p62 bodies in the cell. The molecular determinants that govern PB1 domain filament formation in vitro remain to be determined and the role of p62 filaments inside the cell is currently unclear. We here determine four high-resolution cryo-EM structures of different human ...
