  2. 1. Mechanisms for control of nucleoside triphosphate hydrolysis. Effects of DNA and RNA co-factors

    Author : Bertil Macao; Göteborgs universitet; []
    Keywords : ATPase; GTPase; SRP; Ffh; FtsY; SRP RNA; OBP; UL9; oriS; oriS*; HSV-1; helicase.;

    Abstract : In energetically unfavourable biological processes "protein machines" utilize chemical energy from the hydrolysis of high-energy phosphate bonds. Thus, the hydrolysis of a nucleoside triphosphate (NTP) to nucleoside diphosphate (NDP) with the release of free orthophosphate results in a liberation of energy. READ MORE

  4. 2. A Few Strokes to the Family Portrait of Translational GTPases

    Author : Vasili Hauryliuk; Måns Ehrenberg; Richard Buckingham; Uppsala universitet; []
    Keywords : Molecular biology; translation; GTPase; EF-G; eRF3; Molekylärbiologi;

    Abstract : Protein biosynthesis is a core process in all living organisms. Assembly of the protein chain from aminoacids is catalysed by the ribosome, ancient and extremely complex macromolecular machine. READ MORE

  5. 3. RICH-1, a Multifunctional RhoGAP Domain-containing Protein, Involved in Regulation of the Actin Filament System and Membrane-trafficking

    Author : Ninna Richnau; Pontus Aspenström; Carl-Henrik Heldin; Bengt Hallberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Rho GTPase; RhoGAP; actin; BAR domain; membrane-trafficking; formin homology proteins; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : The Rho GTPases, which are related to the Ras family of proto-oncogenes, have been found to have important roles in regulating the morphogenic and migratory properties of eukaryotic cells. In addition, these proteins have been shown to regulate aspects of cell signaling, cell growth, cell division and cell survival. READ MORE

  6. 4. Regulation of GRAF1 membrane sculpting function during cell movement

    Author : Monika K. Francis; Richard Lundmark; Pekka Lappalainen; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Endocytosis; migration; polarisation; tension; CLIC GEEC; GRAF1; Rho GTPase; Cdc42; Rab8; medicinsk biokemi; Medical Biochemistry;

    Abstract : All eukaryotic cells rely on endocytic events to satisfy a constant need for nutrient and fluid uptake from their surroundings. Endocytosis-dependent turnover of cell surface constituents also serves to control signal transduction and establish morphological changes in response to extracellular stimuli. READ MORE

  7. 5. Cytoskeletal Regulation During Embryonic Development in Drosophila melanogaster

    Author : Mojgan Padash; Udo Häckers grupp Utvecklingsbiologi i invertebrater; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Naturvetenskap; Natural science; DRhoGEF2; Actin cytoskeleton; Rho GTPase;

    Abstract : The development of multicellular organisms is associated with extensive rearrangements of cells and tissues. The driving force for these rearrangements is generated by the cell's actin cytoskeleton. During many morphogenetic processes dynamic rearrangement of the actin cytoskeleton is regulated by small GTPases of the Rho-family. READ MORE
