  1. 1. 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

  3. 2. Unique Solutions to Universal Problems : Studies of the Archaeal Cell

    Författare :Erik A. Pelve; Rolf Bernander; Sonja Verena Albers; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Archaea; Cdv; Cell cycle; Cell division; Cell lysis; Crenarchaea; ESCRT-III; Flow cytometry; Microarray; Microscopy; Nitrosopumilus; SIRV2; Sulfolobus; Thaumarchaea; Transcription; VAP; Virus; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Sammanfattning : Archaea is one of the three domains of life and studies of archaeal biology are important for understanding of life in extreme environments, fundamental biogeochemical processes, the origin of life, the eukaryotic cell and their own, unique biology. This thesis presents four studies of the archaeal cell, using the extremophilic Sulfolobus and ocean living Nitrosopumilus as model systems. LÄS MER

  4. 3. Adhesion-dependent mechanisms regulating mitosis

    Författare :Deepesh Kumar Gupta; Staffan Johansson; Kaisa Haglund; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cytokinesis; Centrosome; Septin; Abscission; Mitosis; Integrin; Adhesion; Binucleation; Biokemi; Biochemistry;

    Sammanfattning : Integrin-mediated cell adhesion is required for normal cell cycle progression during G1-S transition and for the completion of cytokinesis. Cancer cells have ability to grow anchorage-independently, but the underlying mechanisms and the functional significance for cancer development are unclear. LÄS MER

  5. 4. Non-canonical ATG8 conjugation in ESCRT-driven membrane remodeling processes

    Författare :Anastasia Knyazeva; Yao-Wen Wu; Richard Lundmark; Sascha Martens; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ATG8 conjugation; Endosomal Sorting Complex Required for Transport; membrane remodeling; chemical genetics;

    Sammanfattning : ATG8 family proteins have the unique ability to conjugate to membrane lipids. Initially identified as a hallmark of autophagy, ATG8 lipidation is emerging as an important regulator of a growing list of non-degradative cellular functions. LÄS MER

  7. 5. Regulation of Aquaporins by Proteins, Metal ions and Phosphate groups

    Författare :Stefan Kreida; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aquaporin-2; aquaporin-0; calmodulin; LIP5; phosphorylation; calcium; zinc; protein-protein interactions; aquaporin regulation; trafficking; gating;

    Sammanfattning : Aquaporins (AQPs) are membrane-bound intrinsic water channels that allow the passive diffusion of water and small solutes across cellular membranes. There are 13 highly conserved isoforms of these channels in human, which differ in specificity, regulation and localisation in cells and tissues. LÄS MER
