  2. 1. Molecular principles of protein stability and protein-protein interactions

    Author : Christofer Lendel; Per-Åke Nygren; Christopher M. Dobson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; affibody; binding thermodynamics; induced fit; molten globule; NMR spectroscopy; protein engineering; protein-protein interactions; protein stability; protein structure.; Structural biochemistry; Strukturbiokemi;

    Abstract : Proteins with highly specific binding properties constitute the basis for many important applications in biotechnology and medicine. Immunoglobulins have so far been the obvious choice but recent advances in protein engineering have provided several novel constructs that indeed challenge antibodies. READ MORE

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

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

    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

  5. 3. Protein dynamics: aggregation and mechanical unfolding

    Author : Simon Mitternacht; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo simulations; All-atom protein models; Mechanical unfolding; Protein aggregation;

    Abstract : The subject of this thesis is protein dynamics. Papers I--IV and VI study either of two different processes: mechanical unfolding and aggregation. Paper V presents a computationally efficient all-atom model for proteins, variants of which are used to perform Monte Carlo simulations in the other papers. READ MORE

  6. 4. Angiopoietin-like protein 4 : an unfolding chaperone regulating lipoprotein lipase activity

    Author : Valentina Sukonina; Gunilla Olivecrona; Lena Kjellen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lipoprotein lipase; angiopoietin-like protein 4; protein folding; human adipose tissue; macrophages; peroxisome proliferator-activated receptor delta PPARδ ; Medical microbiology; Medicinsk mikrobiologi;

    Abstract : Lipoprotein lipase (LPL) is the main enzyme hydrolyzing triglyceride-rich lipoproteins in plasma. Proteoglycan-bound LPL on the vascular endothelium represent the functional pool of active enzyme. LPL is regulated in a tissue specific manner according to metabolic demands. READ MORE

  7. 5. Exploring small heat shock protein chaperones by crosslinking mass spectrometry

    Author : Wietske Lambert; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cross-linking; mass spectrometry; protein-protein interactions; Hsp21; BS3; DTSSP; MALDI-TOF TOF; client protein; substrate; aggregation; unfolded protein; chaperone; Small heat shock protein; crosslinking;

    Abstract : Together with other molecular chaperones, small heat shock proteins are key components of the protein quality control system, which is comprised of several hundred proteins and acts to maintain proteome homeostasis in the cell. Small heat shock proteins bind unfolding proteins at an early stage, to prevent these from further unfolding and aggregating. READ MORE
