The Intrinsically Disordered Proteins of Myelin in Health and Disease

In the central and peripheral nervous systems, various proteins that contribute to the formation and stability of myelin are present, which also harbor pathophysiological roles in myelin disease. Many myelin proteins have common attributes, including small size, hydrophobic segments, multifunctionality, longevity, and regions of intrinsic disorder. With recent advances in protein biophysical characterization and bioinformatics, it has become evident that intrinsically disordered proteins (IDPs) are abundant in myelin, and their flexible nature enables multifunctionality. Here, we review known myelin IDPs, their conservation, molecular characteristics and functions, and their disease relevance, along with open questions and speculations. We place emphasis on classifying the molecular details of IDPs in myelin, and we correlate these with their various functions, including susceptibility to post-translational modifications, function in protein–protein and protein–membrane interactions, as well as their role as extended entropic chains. We discuss how myelin pathology can relate to IDPs and which molecular factors are potentially involved. Keywords: myelin; intrinsically disordered protein; multiple sclerosis; peripheral neuropathies; myelination; protein folding; protein–membrane interaction; protein–protein interaction 1. -

Radial sorting is a prerequisite for myelination and is arrested in human neuropathies because of laminin deficiency. Experiments in mice using targeted mutagenesis have confirmed that laminins 211, 411, and receptors containing the 1 integrin subunit are required for radial sorting; however, which of the 11 ␣ integrins that can pair with 1 forms the functional receptor is unknown. -

Ras-Associated, Small GTP-Binding Protein Mouse, Recombinant, E. Coli
Rab3AGST-His Ras-associated, small GTP-binding protein mouse, recombinant, E. coli Cat. No. Amount Description: N-terminal tagged Rab3A is a small GTPase that belongs to the Ras PR-115 50 µg superfamily. Rab proteins play an important role in various aspects of membrane traffic, including cargo selection, vesicle budding, vesicle motility, tethering, docking, and fusion. Rab3A, a member of For in vitro use only! the Rab small G protein family, is involved in the process of Ca2+- dependent neurotransmitter release. Rab3A activity is regulated by Shipping: shipped on dry ice a GDP/GTP exchange protein (Rab3 GEP), a Rab GDP dissociation inhibitor (Rab GDI), and a GTPaseactivating protein (Rab3 GAP). Storage Conditions: store at -80 °C The Rab3A recycling is coupled with synaptic vesicle trafficking as follows: (i) GDP-Rab3A forms an inactive complex with Rab GDI and Additional Storage Conditions: avoid freeze/thaw cycles stays in the cytosol of nerve terminals. (ii) GDPRab3A released from Shelf Life: 12 months Rab GDI is converted to GTPRab3A by Rab3 GEP. (iii) GTP-Rab3A binds effector molecules, Rabphilin-3 and Rim, localized at synaptic Molecular Weight: 54 kDa vesicles and the active zone, respectively. These complexes facilitate Accession number: NM_009001 translocation and docking of the synaptic vesicles to the active zone.

How Does Protein Zero Assemble Compact Myelin?

Arne Raasakka 1,* and Petri Kursula 1,2 1 Department of Biomedicine, University of Bergen, Jonas Lies vei 91, NO-5009 Bergen, Norway 2 Faculty of Biochemistry and Molecular Medicine & Biocenter Oulu, University of Oulu, Aapistie 7A, FI-90220 Oulu, Finland; [email protected] * Correspondence: [email protected] Abstract: 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 that concentrically encloses long axonal segments. Schwann cells, the myelinating glia of the PNS, express P0 throughout their development until the formation of mature myelin. In the intramyelinic compartment, the immunoglobulin-like domain of P0 bridges apposing membranes together via homophilic adhesion, forming a dense, macroscopic ultrastructure known as the intraperiod line. The C-terminal tail of P0 adheres apposing membranes together in the narrow cytoplasmic compartment of compact myelin, much like myelin basic protein (MBP). In mouse models, the absence of P0, unlike that of MBP or P2, severely disturbs the formation of myelin. Therefore, P0 is the executive molecule of PNS myelin maturation. How and when is P0 trafficked and modified to enable myelin compaction, and how disease mutations that give rise to incurable peripheral neuropathies alter the function of P0, are currently open questions. The potential mechanisms of P0 function in myelination are discussed, providing a foundation for the understanding of mature myelin development and how it derails in peripheral neuropathies. -
