Examples of cell movement in cytoskeleton
WebThe cytoskeleton is a dynamic network of protein filaments that defines the structure and motility of the cell (Figure 2 ). It prevents deformation of the cell, while allowing for cell-mediated changes in structure including contraction and cell migration. The cytoskeleton is involved in cellular signaling and mediates chromosome segregation ... WebNov 25, 1997 · Many of the movements, both cellular and subcellular, of eukaryotic cells are generated by the activities of motor proteins that act upon rigid cytoskeletal fibers. Three superfamilies of cytoskeletal motor proteins have been recognized. Motors of the myosin superfamily act upon actin filaments to generate cell surface contractions and other ...
