    • Cryo-EM, X-ray diffraction, and atomistic simulations reveal determinants for the formation of a supramolecular myelin-like proteolipid lattice 

      Ruskamo, Salla; Krokengen, Oda Caspara; Kowal, Julia; Nieminen, Tuomo; Lehtimäki, Mari; Raasakka, Arne; Dandey, Venkata P; Vattulainen, Ilpo; Stahlberg, Henning; Kursula, Petri (Journal article; Peer reviewed, 2020)
      Myelin protein P2 is a peripheral membrane protein of the fatty acid–binding protein family that functions in the formation and maintenance of the peripheral nerve myelin sheath. Several P2 gene mutations cause human ...

    • Flexible Players within the Sheaths: The Intrinsically Disordered Proteins of Myelin in Health and Disease 

      Raasakka, Arne; Kursula, Petri (Journal article; Peer reviewed, 2020)
      Myelin ensheathes selected axonal segments within the nervous system, resulting primarily in nerve impulse acceleration, as well as mechanical and trophic support for neurons. In the central and peripheral nervous systems, ...

    • High-affinity anti-Arc nanobodies provide tools for structural and functional studies 

      Markusson, Sigurbjörn; Hallin, Erik Ingmar; Bustad, Helene J.; Raasakka, Arne; Xu, Ju; Muruganandam, Gopinath; Loris, Remy; Martinez, Aurora; Bramham, Clive Raymond Evjen; Kursula, Petri (Journal article; Peer reviewed, 2022)
      Activity-regulated cytoskeleton-associated protein (Arc) is a multidomain protein of retroviral origin with a vital role in the regulation of synaptic plasticity and memory formation in mammals. However, the mechanistic ...

    • How Does Protein Zero Assemble Compact Myelin? 

      Raasakka, Arne; Kursula, Petri (Journal article; Peer reviewed, 2020-08)
      Myelin protein zero (P0), a type I transmembrane protein, is the most abundant protein in peripheral nervous system (PNS) myelin—the lipid-rich, periodic structure of membrane pairs that concentrically encloses long axonal ...

    • Human myelin proteolipid protein structure and lipid bilayer stacking 

      Ruskamo, Salla; Raasakka, Arne; Pedersen, Jan Skov; Martel, Anne; Škubník, Karel; Darwish, Tamim; Porcar, Lionel; Kursula, Petri (Journal article; Peer reviewed, 2022)
      The myelin sheath is an essential, multilayered membrane structure that insulates axons, enabling the rapid transmission of nerve impulses. The tetraspan myelin proteolipid protein (PLP) is the most abundant protein of ...

    • Structural and biophysical characterization of transcription factor HNF-1A as a tool to study MODY3 diabetes variants 

      Kind, Laura; Raasakka, Arne; Molnes, Janne; Aukrust, Ingvild; Bjørkhaug, Lise; Njølstad, Pål Rasmus; Kursula, Petri; Arnesen, Thomas (Journal article; Peer reviewed, 2022)
      Hepatocyte nuclear factor 1A (HNF-1A) is a transcription factor expressed in several embryonic and adult tissues, modulating the expression of numerous target genes. Pathogenic variants in the HNF1A gene are known to cause ...

    • Structural insights into Charcot–Marie–Tooth disease-linked mutations in human GDAP1 

      Sutinen, Aleksi; Nguyen, Giang Thi Tuyet; Raasakka, Arne; Muruganandam, Gopinath; Loris, Remy; Ylikallio, Emil; Tyynismaa, Henna; Bartesaghi, Luca; Ruskamo, Salla; Kursula, Petri (Journal article; Peer reviewed, 2022)
      Charcot–Marie–Tooth disease (CMT) is the most common inherited peripheral polyneuropathy in humans, and its different subtypes are linked to mutations in dozens of different genes. Mutations in ganglioside-induced ...

    • Structure of the ALS Mutation Target Annexin A11 Reveals a Stabilising N-Terminal Segment 

      Lillebostad, Peder August Gudmundsen; Raasakka, Arne; Hjellbrekke, Silje Johannessen; Patil, Sudarshan; Røstbø, Trude Kvalnes; Hollås, Hanne; Sakya, Siri; Szigetvari, Peter Daniel; Vedeler, Anni; Kursula, Petri (Journal article; Peer reviewed, 2020)
      The functions of the annexin family of proteins involve binding to Ca2+, lipid membranes, other proteins, and RNA, and the annexins share a common folded core structure at the C terminus. Annexin A11 (AnxA11) has a long ...

    • Structure of the Complete Dimeric Human GDAP1 Core Domain Provides Insights into Ligand Binding and Clustering of Disease Mutations 

      Nguyen, Giang Thi Tuyet; Sutinen, Aleksi; Raasakka, Arne; Muruganandam, Gopinath; Loris, Remy; Kursula, Petri (Journal article; Peer reviewed, 2021)
      Charcot-Marie-Tooth disease (CMT) is one of the most common inherited neurological disorders. Despite the common involvement of ganglioside-induced differentiation-associated protein 1 (GDAP1) in CMT, the protein structure ...
