  2. 1. Regulation of tubulin heterodimer partitioning during interphase and mitosis

    Author : Per Holmfeldt; Martin Gullberg; Pontus Aspenström; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; microtubule; mitotic spindle; signal transduction; phosphorylation; cancer; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : The microtubule cytoskeleton, which consists of dynamic polymers of alpha/beta tubulin heterodimers, organizes the cytoplasm and is essential for chromosome segregation during mitosis. My thesis addresses the significance and potential interplay between four distinct microtubule-regulatory proteins. READ MORE

  4. 2. Characterization of New Players in Planar Polarity Establishment in Arabidopsis

    Author : Stefano Pietra; Markus Grebe; Niko Geldner; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SABRE; planar polarity; CLASP; cell division orientation; microtubule cytoskeleton; actin; AIP1; patterning; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Abstract : Coordinated polarity and differentiation of cells in the plane of a tissue layer are essential to the development of multicellular organisms. Arabidopsis thaliana root hairs and trichomes provide model systems to study the pathways that control planar polarity and cell fate specification in plants. READ MORE

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

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

    Abstract : 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. READ MORE

  6. 4. Cytoskeletal filament systems : assembly, regulation, and interplay in mammalian cells

    Author : Mikael E Sellin; Martin Gullberg; Jeremy Thorner; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cell research; cellforskning;

    Abstract : The cell represents the basic unit of structure and function for all life. The interior of a eukaryotic cell is organized by an extensive array of protein filaments – collectively referred to as the cytoskeleton. These filaments serve diverse essential functions, e.g. READ MORE

  7. 5. The roles of inner nuclear membrane proteins during interphase and mitosis

    Author : Veronica J. Larsson; Einar Hallberg; Neus Visa; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Samp1; mitotic spindle; centrosome; LINC complex; Lamina; Sun1; mitosis; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : The nuclear envelope (NE) consists of two concentric membranes, the outer nuclear membrane (ONM) and the inner nuclear membrane (INM). The LINC (linker of nucleoskeleton and cytoskeleton) complex spans both the ONM and the INM connecting the cytoskeleton to the nucleoskeleton and chromatin. READ MORE
