Prokaryotic cytoskeleton

Elements of the Caulobacter crescentus cytoskeleton. The prokaryotic cytoskeletal elements are matched with their eukaryotic homologue and hypothesized cellular function.[1]

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.[2] Not only have analogues for all major cytoskeletal proteins in eukaryotes been found in prokaryotes, cytoskeletal proteins with no known eukaryotic homologues have also been discovered.[3][4][5][6] Cytoskeletal elements play essential roles in cell division, protection, shape determination, and polarity determination in various prokaryotes.[7][8]
