  1. 1. The p97 ATPase and the Drosophila Proteasome : Protein Unfolding and Regulation

    Author : Kristian Björk Grimberg; Patrick Young; Neus Visa; Lars Thelander; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; proteasome; ubiquitin; p97; unfolding; regulation; RNAi screen; high-throughput screen; cnc; basic leucine zipper; transcription factors; proteasome inhibition; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : For all living systems, there is a requirement to recycle and regulate proteins. In eukaryotic organisms this is accomplished by the proteasome. The p97 ATPase is another highly conserved and essential complex present throughout the eukaryotic cell. READ MORE

  2. 2. Functional analysis of the proteasome in eukaryotic organisms

    Author : Marianthi Sakellari; Efstathios S. Gonos; Allan Sirsjö; Richard G. A. Faragher; Örebro universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Proteasome; Proteasome activation; Protein synthesis inhibition; Hsp70; Hsp90; Proteostasis; Aging; Alzheimer’s disease; Caenorhabditis elegans; Lifespan extension; SKN-1;

    Abstract : Proteasome degradation machinery is responsible for the turnover of a huge variety of normal and abnormal proteins, thus regulating a plethora of cellular processes. Aging is an inevitable biological process that is characterized by reduced proteasome function that leads to proteotoxic stress. READ MORE

  3. 3. Investigating the activation and regulation of the proteasome : an essential proteolytic complex

    Author : Patrick Masson; Patrick Young; Marcus Groettrup; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Proteasome; PA28gamma; Transcriptional regulation; Drosophila; 26S; Molecular biology; Molekylärbiologi;

    Abstract : The proteasome is a major non-lysosomal proteolytic complex present in eukaryotic cells and has a central role in regulating many protein levels. The complex has been shown to participate in various intracellular pathways including cell cycle regulation or quality control of newly synthesized proteins and many other key pathways. READ MORE

  4. 4. Protein Damage Control during Embryonic Stem Cell Differentiation: Role of the Proteasome

    Author : Malin Hernebring; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Embryonic Stem Cells; Proteasome; Protein Carbonylation; Advanced Glycation End products; Cell Differentiation; Oxidative stress; Aging; RNAi;

    Abstract : During the lifespan of organisms ranging from yeast to humans, there is an accumulation of macromolecular damage. However, these organisms produce youthful progeny with low damage levels. This thesis focuses on how this is accomplished. READ MORE

  5. 5. The Path to Destruction : Understanding the mechanism and regulation of proteasomal degradation

    Author : Anne Beskow; Patrick Young; Ylva Engström; Bernat Crosas; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Proteasome; ubiquitin; p97; Cnc-C; transcription factors; Nrf1; Nrf2; molekylärbiologi; Molecular Biology;

    Abstract : A majority of intracellular proteins are degraded by the ubiquitin proteasome system (UPS). In this thesis, both the mechanism of the degradation and the regulation of UPS have been investigated. The importance of the p97 ATPase for proteasomal degradation of cytosolic substrates was examined. READ MORE
