1. 1. Modeling and simulation of intrinsically disordered proteins

   Författare :Joao Henriques; Beräkningskemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Intrinsically disordered proteins; Coarse-grained models; Atomistic models; Metropolis Monte Carlo simulations; Molecular dynamics simulations; Sampling; Conformational analysis; Charge regulation; Surface adsorption;

   Sammanfattning : This work is primarily about the development, validation and application of computer simulation models for intrinsically disordered proteins, both in solution and in the presence of uniformly charged, ideal surfaces. The models in question are either coarse-grained or atomistic in nature, and their applications are dependent on the specific purpose of each study. LÄS MER

3. 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.

4. 3. Molecular properties of disordered plant dehydrins : Membrane interaction and function in stress

   Författare :Sylvia Eriksson; Pia Harryson; Steffen Graether; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; abiotic stress; dehydrin; intrinsically disordered proteins; Lea-proteins; phospholipids; Biochemistry; biokemi;

   Sammanfattning : Dehydrins are intrinsically disordered plant stress-proteins. Repetitively in their sequence are some highly conserved stretches of 7-17 residues, the so called K-, S-, Y- and lysine rich segments. LÄS MER

5. 4. 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.

7. 5. 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.
