WebCytoskeleton elements get their name from the fact that their diameter, 8 to 10 nm, is between those of microfilaments and microtubules. Figure 4.24 Intermediate filaments consist of several intertwined strands of fibrous proteins. Intermediate filaments have no role in cell movement. Their function is purely structural. WebHowever, this notion changed drastically in the 1990s, with observations of cytoskeleton-like structures in several prokaryotes. Homologs of the main components of eukaryotic cytoskeletons, such as microtubules, microfilaments, and intermediate filaments, have been identified in bacteria and archaea.
