WebThe cytoskeleton is the protein framework within the cytoplasm that links, anchors, or tethers structural components inside the cell.18,21 Microfilaments (actin filaments), microtubules, and intermediate filaments are three classes of cytoskeleton proteins found in the cytoplasm. The prokaryotic cytoskeleton is the collective name for all structural filaments in prokaryotes. It was once thought that prokaryotic cells did not possess cytoskeletons, but advances in visualization technology and structure determination led to the discovery of filaments in these cells in the early 1990s. … See more FtsZ FtsZ, the first identified prokaryotic cytoskeletal element, forms a filamentous ring structure located in the middle of the cell called the Z-ring that constricts during cell division, … See more MreB MreB is a bacterial protein believed to be homologous to eukaryal actin.
