  1. 6. The G protein-coupled receptor GPR30 signalosome - A novel G protein-independent mechanism regulating cAMP signaling and receptor trafficking

    Författare :Stefan Broselid; Drug Target Discovery; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AKAP5; AKAP; MAGUK; cAMP signaling; constitutive signaling; signalosome; GPER; GPR30; GPCR; cytokeratin; RAMP3; apoptotic signaling; breast cancer; PDZ; PDZ-ligand;

    Sammanfattning : The large protein family called G Protein-coupled receptors (GPCRs) has co-evolved with life throughout evolution; from single cell organisms all the way to complex beings such as us humans. The fact that GPCRs are involved in essentially every physiological event, and that ~50% of drugs on the current market are either directly or indirectly targeted towards the function of GPCRs, we can be certain of their considerable importance.

  3. 7. Membrane Stress and the Role of GYF Domain Proteins

    Författare :Alexander Georgiev; Åke Wieslander; Hana Sychrova; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SYH1; SMY2; YPT6; RIC1; MYR1; processing bodies; vesicular trafficking; lipid bilayer; budding yeast; GYF; membrane stress; mRNA decay; Saccharomyces cerevisiae; Biochemistry; Biokemi; biokemi; Biochemistry;

    Sammanfattning : Intracellular membrane trafficking is regulated by a large number of protein complexes and lipids. Blocking of trafficking disrupts normal membrane dynamics and causes membrane stress. LÄS MER

  4. 8. Cell signaling by Rho and Miro GTPases : Studies of Rho GTPases in Cytoskeletal Reorganizations and of Miro GTPases in Mitochondrial Dynamics

    Författare :Åsa Fransson; Pontus Aspenström; Harry Mellor; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ras superfamily; Rho GTPases; cytoskeleton; Miro GTPases; mitochondrial dynamics; Cell and molecular biology; Cell- och molekylärbiologi;

    Sammanfattning : The Ras superfamily of GTPases embraces six major branches of proteins: the Ras, Rab, Ran, Arf, Rho and Miro subfamilies. The majority of GTPases function as binary switches that cycle between active GTP-bound and inactive GDP-bound states. This thesis will focus primarily on the biological functions of the Rho and Miro proteins. LÄS MER

  5. 9. Functional characterization of interactions between the flavivirus NS5 protein and PDZ proteins of the mammalian host

    Författare :Karin Ellencrona; Magnus Johansson; Andrew Davidson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tick-borne encephalitis virus TBEV ; West-Nile virus WNV ; Dengue virus DENV ; flavivirus; PDZ domains; ZO-2; ZO-1; RIMS2; Scribble; Interferon; JAK-STAT signaling; PDZ array; virus-host protein interaction; Genetics; Genetik; molekylärgenetik; Molecular Genetics;

    Sammanfattning : Flaviviruses are found all over the world and affect and infect millions of people every year. Flavivirus infection can lead to severe clinical outcomes resulting in neuronal damages e.g. Tick-borne encephalitis virus (TBEV), or severe hemorrhagic fevers e. LÄS MER

  7. 10. Plasma Membrane Proteomics and Functional Characterization & Expression Profiling of Plant Aquaporins

    Författare :Erik Alexandersson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; Plant biochemistry; phosphorylation; barley; GFP; GUS; quantitative real-time reverse transcriptase PCR; microarray; aquaporin; MIP; Arabidopsis; plasma membrane; proteomics;

    Sammanfattning : In order to identify integral and peripheral proteins associated with the plasma membrane (PM), highly purified Arabidopsis PMs were analyzed by mass spectrometry. In total, 238 putative PM proteins were identified, of which 114 were predicted to have transmembrane domains or to be PM-anchored. LÄS MER
