Cytoskeleton bacteria
WebMay 3, 2010 · In bacteria, proteins homologous to all three classes of eukaryotic cytoskeletal filaments have recently been discovered. These proteins are essential for the maintenance of bacterial cell shape and have been shown to guide the localization of key cell-wall-modifying enzymes. WebThe cytoskeleton is involved in cellular signaling and mediates chromosome segregation and cytokinesis in mitosis. It affects intracellular movement of organelles and vesicles and serves as a scaffold for cellular contents, interacting heavily with the plasma membrane.
