Smallest element of the cytoskeleton
Webb10 apr. 2024 · Microtubules are the largest of the three cytoskeleton components, with a diameter ranging from 15 to 20 nm. Microtubules, unlike microfilaments, consist of a single type of globular protein known as tubulin (a protein made up of kd polypeptides and alpha and beta tubulin). WebbCytoskeleton 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.
