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

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

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

4. Regulation of GRAF1 membrane sculpting function during cell movement
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

5. Cytoskeletal Regulation During Embryonic Development in Drosophila melanogaster
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
