  2. 16. A Chloroplast Localized Small Heat Shock Protein, Hsp21. Importance of Hsp21 in stress protection of transgenic Arabidopsis thaliana, recombinant expression and characterization of oxidation-dependent conformational changes

    Author : Ulrika Härndahl; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; a-crystallin; sHsp; chaperone; amphipathic a-helix; oligomer; redox-regulated; methionine sulfoxidation; oxidative stress; regulation; protein structure; circular dichroism; mass spectrometry; fluorescence spectroscopy; Biochemistry; Metabolism; Biokemi;

    Abstract : A specific group of heat shock proteins, the so called small heat shock proteins (sHsps), exists in all organisms but are especially abundant in plants. The sHsps prevent aggregation of other proteins (substrate proteins) during transient heat and oxidative stress. READ MORE

  5. 18. Mapping ultrastructural effects of proteotoxic stress on S. cerevisiae

    Author : Katharina Keuenhof; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; yeast; heat shock; stress; electron microscopy; ultrastructure; nuclear envelope budding;

    Abstract : Cells are the basic building blocks of any living being, whether the organism consists of only one, or many cells. The different cellular components interact with one another to maintain the viability of the cell. An essential element of cells are proteins – peptide chains folded into a specific conformation unique to every protein. READ MORE

  6. 19. Structural studies of microbubbles and molecular chaperones using transmission electron microscopy

    Author : Johan Härmark; Philip JB Köck; Hans Hebert; Reinhard Rachel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Transmission electron microscopy; Contrast agent; Microbubble; Polyvinyl alcohol; Single particle analysis; Heat shock protein; Molecular chaperone; Technology and Health; Teknik och hälsa;

    Abstract : Ultrasound contrast agents (CAs) are typically used in clinic for perfusion studies (blood flow through a specific region) and border delineating (differentiate borders between tissue structures) during cardiac imaging. The CAs used during ultrasound imaging usually consist of gas filled microbubbles (MBs) (diameter 1-5 μm) that are injected intravenously into the circulatory system. READ MORE

  7. 20. Regulation of Hsp70 function by nucleotide-exchange factors

    Author : Naveen Kumar Chandappa Gowda; Claes Andréasson; Gary Jones; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Heat shock proteins Hsps ; Hsp70; Molecular chaperones; Nucleotide-exchange factors NEFs ; Protein quality control PQC ; Proteostasis; Ubiquitin-proteasome system; Cell Biology; cellbiologi;

    Abstract : Protein folding is the process in which polypeptides in their non-native states attain the unique folds of their native states. Adverse environmental conditions and genetic predisposition challenge the folding process and accelerate the production of proteotoxic misfolded proteins. READ MORE
