  3. 2. Mechanism of F-actin crosslinking by filamin A and the anti-inflammatory functions of plasma gelsolin in bodily fluids

    Författare :Teresia Magnuson Osborn; Göteborgs universitet; []
    Nyckelord :Cytoskeleton; Crosslinking; F-actin; Filamin; Gelsolin; Inflammation; Plasma; Platelet-activating factor; Lysophosphatidic acid; Rheumatoid arthritis;

    Sammanfattning : Gelsolin (GSN) and filamin A (FLNa) are two actin-binding proteins discovered in our laboratory over 30 years ago. GSN is a calcium-activated actin severing and barbed end capping protein that is expressed as both intracellular and extracellular (plasma gelsolin, pGSN) isoforms. LÄS MER

  4. 3. The molecular chaperone CCT: Functions beyond folding

    Författare :Josefine Vallin; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TRiC; Chaperonin; CCT oligomer; CCT monomer; cancer; p150Glued; gelsolin; STAT3;

    Sammanfattning : The chaperonin-containing tailless complex polypeptide 1 (CCT) is a eukaryotic ~1 MDa barrel shaped molecular chaperone, built up by eight distinct subunits and is required for the folding of the abundant cytoskeletal proteins actin and tubulin. CCT exists as an assembled oligomer, micro-complexes and as individual subunits in the cell. LÄS MER

  5. 4. The Extended Role of the Molecular Chaperone CCT

    Författare :Andreas Svanström; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; CCT oligomer; Actin; CCT delta; CCT epsilon; Gelsolin; MRTF-A; Cell morphology;

    Sammanfattning : The oligomeric chaperone CCT is a large ATP-dependent chaperonin that consists of two rings placed back-to-back with eight different paralogous subunits with a size of ~ 55 kDa that sit in each of the two rings. The function of CCT is mainly to fold the abundant proteins actin and tubulin, components of the cytoskeleton. LÄS MER

  7. 5. Divisive structures : Two billions years of biofilament evolution

    Författare :Fredrik Hurtig; Ann-Christin Lindås; Lionel Guy; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Evolution; Archaea; Eukaryogenesis; ESCRT-III; Actin; Profilin; Gelsolin; Asgard; TACK; Sulfolobus; Cell division; Cytokinesis; Cytoskeleton; Heimdallarchaeota; Actin-binding protein; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Our understanding of the functional and regulatory complexity that existed in the eukaryotic progenitor is poor, and investigations have been hindered by our nebulous understanding of where eukaryotes stem from. Recently discovered archaeal lineages with hitherto unseen homology to eukaryotic systems suggest archaea can further our understanding of the eukaryotic cell’s ancestry. LÄS MER
