Smallest protein elements of the cytoskeleton
WebbAs their name implies, microtubules are small hollow tubes. Polymerized dimers of α-tubulin and β-tubulin, two globular proteins, comprise the microtubule’s walls (Figure 3.20). With a diameter of about 25 nm, microtubules are cytoskeletons’ widest components. WebbThe cytoskeleton extends from the nucleus to the cell membrane and is composed of interlocking proteins. In eukaryotic cells, the cytoskeleton includes three main …

Webbhas a cytoskeleton—a kind of a network of support beams that gives the living cell structural reinforce-ment. A microtubule (Figure 1) is a very stiff poly-mer and it is the main constituent of the cytoskeleton. The monomers in a microtubule are proteins that consist of about 800 amino acids. Two conformational states are possible for each ...
