  1. 1. Ligand-activated proteolysis in nutrient signaling

    Författare :Claes Andréasson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Cells respond to changing nutrient availability and make adjustments in physiological processes. Central for making proper adjustments is the ability to execute appropriate changes in patterns of gene expression. LÄS MER

  3. 2. Hsp70 nucleotide exchange factor Fes1 is essential for protein quality control in Saccharomyces cerevisiae

    Författare :Naveen Kumar Chandappa Gowda; Claes Andréasson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Heat shock protein 70; molecular chaperone; ubiquitin; nucleotide exchange factor; protein quality control; Cell Biology; cellbiologi;

    Sammanfattning : .... LÄS MER

  4. 3. Regulation of Hsp70 function by nucleotide-exchange factors

    Författare :Naveen Kumar Chandappa Gowda; Claes Andréasson; Gary Jones; Stockholms universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. Regulation of cellular Hsp70 : Proteostasis and aggregate management

    Författare :Jayasankar Mohanakrishnan Kaimal; Claes Andréasson; Pierre Goloubinoff; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Proteins have to be folded to their native structures to be functionally expressed. Misfolded proteins are proteotoxic and negatively impact on cellular fitness. To maintain the proteome functional proteins are under the constant surveillance of dedicated molecular chaperones that perform protein quality control (PQC). LÄS MER

  7. 5. Controlling protein homeostasis through regulation of Heat shock factor 1

    Författare :Anna E. Masser; Claes Andréasson; Marie Öhman; David Pincus; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; stress; protein homeostasis; molecular chaperones; heat shock response; Hsf1; Hsp70; Saccharomyces cerevisiae; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : In order to thrive in a changing environment all organisms need to ensure protein homeostasis (proteostasis). Proteostasis is ensured by the proteostasis system that monitors the folding status of the proteome and regulates cell physiology and gene expression to counteract any perturbations. LÄS MER
