  1. 1. Advanced Fluorescence Microscopy to Study Plasma Membrane Protein Dynamics

    Detta är en avhandling från Lausanne : EPFL

    Författare :Joachim Piguet; Horst Vogel; Ruud Hovius; Jerker Widengren; Antoine Triller; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fluorescence; microscopy; plasma membrane; membrane proteins; membrane proteins diffusion; single-molecule imaging; single-molecule tracking; pentameric ligand-gated ion channels; nicotinic acetylcholine receptor; serotonin receptor; synapse; neuromuscular junction; post-synaptic scaffold; rapsyn; myopathies; fluorescent proteins; Förster resonance energy transfer; FRET imaging; protein-protein interactions; protein trafficking; photo-activatable proteins; Biologisk fysik; Biological Physics;

    Sammanfattning : Membrane protein dynamics is of great importance for living organisms. The precise localization of proteins composing a synapse on the membrane facing a nerve terminus is essential for proper functioning of the nervous system. In muscle fibers, the nicotinic acetylcholine is densely packed under the motor nerve termini. LÄS MER

  2. 2. Membrane protein topogenesis

    Detta är en avhandling från Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Författare :Karin Öjemalm; Gunnar von Heijne; Tracy Palmer; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Sammanfattning : The membranes of cells are highly complex and heterogeneous structures that fulfill multiple vital tasks. They form thin barriers that seal out the environment, thus defining the cell’s boundaries. LÄS MER

  3. 3. Membrane-bound proteins Characterization, evolution, and functional analysis

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Misty M. Attwood; Helgi B. Schiöth; Arne Elofsson; [2020]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Transmembrane protein; alpha-helical membrane protein; evolution membrane proteins; 3TM; 4TM; 5TM; trispanin; Bioinformatics; Bioinformatik;

    Sammanfattning : Alpha-helical transmembrane proteins are important components of many essential cell processes including signal transduction, transport of molecules across membranes, protein and membrane trafficking, and structural and adhesion activities, amongst others. Their involvement in critical networks makes them the focus of interest in investigating disease pathways, as candidate drug targets, and in evolutionary analyses to identify homologous protein families and possible functional activities.

  4. 4. Exploring the Interplay of Lipids and Membrane Proteins

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Candan Ariöz; Åke Wieslander; Daniel O. Daley; Malcolm East; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Membrane lipids; membrane proteins; anionic lipids; membrane remodeling; intracellular vesicles; model membrane systems; glycosyltransferase; Escherichia coli; lipid composition; fatty acid modification; membrane curvature; bacterial homeoviscous adaptation; biokemi; Biochemistry;

    Sammanfattning : The interplay between lipids and membrane proteins is known to affect membrane protein topology and thus have significant effect (control) on their functions. In this PhD thesis, the influence of lipids on the membrane protein function was studied using three different membrane protein models. LÄS MER

  5. 5. Protein and lipid interactions within the respiratory chain Studies using membrane-mimetic systems

    Detta är en avhandling från Stockholm : Department of Biochemistry and Biophysics, Stockholm University

    Författare :Tobias Nilsson; Peter Brzezinski; Petra Hellwig; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cytochrome c oxidase; ATP synthase; Bioenergetics; membrane-mimetics; Rcf1; liposomes; oxidative phosphorylation; lipids; protein-protein interactions; biokemi; Biochemistry;

    Sammanfattning : Energy conversion from nutrients to ATP is a vital process in cells. The process, called oxidative phosphorylation (OXPHOS) is performed by a combination of membrane-bound proteins. These proteins have been studied in great detail in the past, however much is still unknown about how they interact with each other. LÄS MER
