• Membrane Association Landscape of Myelin Basic Protein Portrays Formation of the Myelin Major Dense Line 

      Raasakka, Arne; Ruskamo, Salla; Kowal, Julia; Barker, Robert; Baumann, Anne; Martel, Anne; Tuusa, Jussi; Myllykoski, Matti; Bürck, Jochen; Ulrich, Anne S.; Stahlberg, Henning; Kursula, Petri (Peer reviewed; Journal article, 2017-07-10)
      Compact myelin comprises most of the dry weight of myelin, and its insulative nature is the basis for saltatory conduction of nerve impulses. The major dense line (MDL) is a 3-nm compartment between two cytoplasmic leaflets ...
    • Molecular mechanisms of Charcot-Marie-Tooth neuropathy linked to mutations in human myelin protein P2 

      Ruskamo, Salla; Nieminen, Tuomo; Kristiansen, Cecilie Katrin; Vatne, Guro Helén; Baumann, Anne; Hallin, Erik Ingmar; Raasakka, Arne; Joensuu, Päivi; Bergmann, Ulrich; Vattulainen, Ilpo; Kursula, Petri (Peer reviewed; Journal article, 2017-07-26)
      Charcot-Marie-Tooth (CMT) disease is one of the most common inherited neuropathies. Recently, three CMT1-associated point mutations (I43N, T51P, and I52T) were discovered in the abundant peripheral myelin protein P2. These ...
    • Molecular structure and function of myelin protein P0 in membrane stacking 

      Raasakka, Arne; Ruskamo, Salla; Kowal, Julia; Han, Huijong; Baumann, Anne; Myllykoski, Matti; Fasano, Anna; Rossano, Rocco; Riccio, Paolo; Bürck, Jochen; Ulrich, Anne S.; Stahlberg, Henning; Kursula, Petri (Peer reviewed; Journal article, 2019)
      Compact myelin forms the basis of nerve insulation essential for higher vertebrates. Dozens of myelin membrane bilayers undergo tight stacking, and in the peripheral nervous system, this is partially enabled by myelin ...
    • Myelin-derived and putative molecular mimic peptides share structural properties in aqueous and membrane-like environments 

      Tuusa, Jussi; Raasakka, Arne; Ruskamo, Salla; Kursula, Petri (Peer reviewed; Journal article, 2017-03-24)
      Background: Despite intense research, the causes of various neurological diseases remain enigmatic to date. A role for viral or bacterial infection and associated molecular mimicry has frequently been suggested in the ...
    • Neuropathy-related mutations alter the membrane binding properties of the human myelin protein P0 cytoplasmic tail 

      Raasakka, Arne; Ruskamo, Salla; Barker, Robert; Krokengen, Oda Caspara; Vatne, Guro Helén; Kristiansen, Cecilie Katrin; Hallin, Erik Ingmar; Skoda, Maximilian W. A.; Bergmann, Ulrich; Wacklin-Knecht, Hanna; Jones, Nykola C; Hoffmann, Søren V; Kursula, Petri (Peer reviewed; Journal article, 2019-06-07)
      Schwann cells myelinate selected axons in the peripheral nervous system (PNS) and contribute to fast saltatory conduction via the formation of compact myelin, in which water is excluded from between tightly adhered lipid ...
    • Structure and dynamics of a human myelin protein P2 portal region mutant indicate opening of the β barrel in fatty acid binding proteins 

      Laulumaa, Saara; Nieminen, Tuomo; Raasakka, Arne; Krokengen, Oda C.; Safaryan, Anushik; Hallin, Erik Ingmar; Brysbaert, Guillaume; Lensink, Marc F.; Ruskamo, Salla; Vattulainen, Ilpo; Kursula, Petri (Peer reviewed; Journal article, 2018-06-25)
      Background: Myelin is a multilayered proteolipid sheath wrapped around selected axons in the nervous system. Its constituent proteins play major roles in forming of the highly regular membrane structure. P2 is a myelin-specific ...
