  1. 1. Metal Binding Tags - Characterisation, Use in Bioseparation and Applications of Green Fluorescent Fusion Proteins

    Författare :Florent Bernaudat; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Proteiner; enzymologi; enzymology; E. coli; Immobilised metal ion affinity chromatography; Affinity tags; Green fluorescent protein; Surface plasmon resonance; Genetic engineering; Screening; Proteins; Immunoassay; Biotechnology; Bioteknik;

    Sammanfattning : Most of the recombinant proteins produced nowadays are fused to affinity tags, in order to facilitate their purification through affinity chromato-graphy. Out the different tags available, poly-histidine tags are among the most commonly used and can help purification through immobilised metal ion affinity chromatography (IMAC). LÄS MER

  2. 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 :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; 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

  3. 3. DNA-Controlled Lipid-Membrane Fusion

    Författare :Lisa Simonsson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; exocytosis; vesicles; DNA; FRET; fluorescence resonance energy transfer; model system; total internal reflection fluorescence microscopy; TIRF microscopy; self-assembly; site-specificity; diffusion; biomembranes; lipid bilayer; membrane fusion;

    Sammanfattning : Membrane fusion is essential for nerve-cell communication, for protein transport between cell organelles and the cell-membrane and for enabling the merger between virus and host membranes during virus infection. We have demonstrated that short DNA oligonucleotides, membrane-attached via CH in an orientation that mimics the overall zipperlike architecture of fusion-inducing proteins, induce fusion of both suspended vesicles and vesicles site-specifically tethered to SLBs.

  4. 4. Endoplasmic Reticulum Dynamic Structural Changes in Neurons: The Fission-Fusion Phenomena

    Författare :Krzysztof Kucharz; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; fragmentation; fission; endoplasmic reticulum; neurons; FRAP; primary cultures; organotypic slice cultures; in vivo; in situ; calcium; fusion; NMDA receptor; 2-photon microscopy; confocal microscopy;

    Sammanfattning : The endoplasmic reticulum (ER) is crucial for protein synthesis and protein maturation, is involved in cell stress and serves in neurons as the major intracellular Ca2+ store. Neuronal ER forms a continuous network of cisterns and tubules extending from soma to a subset of dendritic spines. LÄS MER

  5. 5. The contribution of proteins and lipids to COPI vesicle formation and consumption

    Författare :Fredrik Kartberg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :ARF1; COPI; ARFGAP; vesicle; fusion; diffusion;

    Sammanfattning : In the secretory pathway, movement of proteins between compartments occurs through small (50-100 nm) vesicles. The coat of COPI vesicles is composed the small GTPase ARF1 and the large coatomer complex. In the secretory pathway, these vesicles mediate Golgi-to-ER and intra-Golgi transport. LÄS MER
