  1. 1. Into the Membrane and Beyond : Improving Membrane Protein Over-Expression in Escherichia coli

    Författare :Mirjam Klepsch; Jan-Willem de Gier; Reinhard Grisshammer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; membrane protein over-expression; proteomics; T7 RNA polymerase; peptide transport; strain engineering; Biochemistry; Biokemi; Biophysical chemistry; Biofysikalisk kemi; biokemi; Biochemistry;

    Sammanfattning : Membrane proteins fulfil a wide variety of essential functions in the cell and many are (potential) drug targets. Since their natural abundance is usually very low, most membrane proteins have to be over-expressed for functional and structural studies. LÄS MER

  3. 2. Advanced Fluorescence Microscopy to Study Plasma Membrane Protein Dynamics

    Författare :Joachim Piguet; Horst Vogel; Ruud Hovius; Jerker Widengren; Antoine Triller; Switzerland Ecole Polytechnique Fédérale de Lausanne (EPFL); []
    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; Biological Physics; Biologisk fysik;

    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

  4. 3. Regulators of Membrane Fluidity

    Författare :Kiran Busayavalasa; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PAQR; LRIG; membrane fluidity;

    Sammanfattning : Caenorhabditis elegans PAQR-2 (a homolog of the mammalian AdipoR1 and AdipoR2 proteins) and IGLR-2 (homolog of the mammalian LRIG proteins) form a complex at the plasma membrane that regulates fatty acid desaturation to protect against saturated fatty acid-induced membrane rigidification. Maintenance of membrane homeostasis is fundamental for most cellular processes and, given its importance, robust regulatory mechanisms must exist that adjust lipid composition to compensate for dietary variation.

  5. 4. Membrane and secretory protein production in Escherichia coli

    Författare :Alexandros Karyolaimos; Jan-Willem de Gier; Matthew DeLisa; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; recombinant protein; tunable protein production; cytoplasmic membrane; periplasm; signal peptide; force profile analysis; co-translational folding; Biochemistry; biokemi;

    Sammanfattning : Escherichia coli (E. coli) is the most widely used bacterium for the production of recombinant proteins. However, the production of proteins in its cytoplasmic membrane or periplasm is challenging. Therefore, the aim of this doctoral thesis was to develop setups for enhancing the production of membrane and secretory proteins in E. LÄS MER

  7. 5. Membrane effects on proton transfer in cytochrome c oxidase

    Författare :Linda Näsvik Öjemyr; Peter Brzezinski; Anthony G. Lee; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cytochrom c oxidase; lipids; membrane; proton transfer; Biochemistry; biokemi;

    Sammanfattning : The biological membrane is composed of lipids and proteins that make up dynamic barriers around cells and organelles. Membrane-spanning proteins are involved in many key processes in the cell such as energy conversion, nerve conduction and signal transduction. LÄS MER
