  1. 1. Biophysical characterization of protein-protein interactions involving intrinsically disordered proteins

    Författare :Ida Nyqvist; Jakob Dogan; Ivarsson Ylva; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Intrinsically disordered proteins; Protein-protein interactions; Disorder-to-order transition; Rate-limiting transition state; Ф-value analysis; NMR relaxation; Side-chain dynamics; Backbone dynamics; Conformational entropy change; Biophysics; biofysik;

    Sammanfattning : Intrinsically disordered proteins and regions (IDPs/Rs) are proteins that do not form stable and well-defined structures in their free states but rather occupy an ensemble of conformations that change over time while still staying functional. They are prevalent in the eukaryotic proteome and are involved in various vital processes in the cell where they often interact with their binding partners through coupled binding and folding reactions.

  2. 2. Evolution of Interactions Involving Intrinsically Disordered Proteins

    Författare :Emma Åberg; Per Jemth; Madan Babu; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; intrinsically disordered proteins; protein evolution; phylogenetics; ancestral sequence reconstruction; biophysical characterization; NCBD; CID; p53; MDM2; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution; Biokemi; Biochemistry;

    Sammanfattning : This thesis describes the evolution of intrinsically disordered proteins and their interaction partners. The work presented is a combination of phylogenetic analysis, ancestral reconstruction and biophysical characterization in order to examine the evolutionary trajectory of protein-protein interactions involving disorder.

  3. 3. Evolution and Binding Mechanisms of Intrinsically Disordered Proteins

    Författare :Elin Karlsson; Per Jemth; Kaare Teilum; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intrinsically disordered proteins; Protein evolution; Binding kinetics; Binding mechanisms; Biophysical characterisation; Medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : Intrinsically disordered proteins (IDPs) make up a considerable fraction of the proteome in eukaryotic organisms. These proteins often act as hubs in interaction networks, harbouring multiple interaction with other proteins, and thus evolution has to walk a tightrope to accommodate new interactions while maintaining the previously established interactions.

  4. 4. Exploring small heat shock protein chaperones by crosslinking mass spectrometry

    Författare :Wietske Lambert; Biokemi och Strukturbiologi; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 5. From protein sequence to structural instability and disease

    Författare :Lixiao Wang; Uwe Sauer; Sven Hovmöller; Umeå universitet; []
    Nyckelord :protein domain; remote homologue; intrinsically disorder unstructured proteins; protein function; point mutation; protein family protein stability; HMMs; CRFs; SVMs;

    Sammanfattning : A great challenge in bioinformatics is to accurately predict protein structure and function from its amino acid sequence, including annotation of protein domains, identification of protein disordered regions and detecting protein stability changes resulting from amino acid mutations. The combination of bioinformatics, genomics and proteomics becomes essential for the investigation of biological, cellular and molecular aspects of disease, and therefore can greatly contribute to the understanding of protein structures and facilitating drug discovery.
