Microtubules are filamentous intracellular structures that are responsible for various kinds of movements in all eukaryotic cells. Microtubules are involved in nucleic and cell division, organization of intracellular structure, and intracellular transport, as well as ciliary and flagellar motility.icrotubules form a framework for structures such as the spindle apparatus that appears during cell division, or the whiplike organelles known as cilia and flagella. Cilia and flagella are the most well-studied models for microtubule structure and assembly, and are often used by textbooks to introduce microtubules.
All cytoskeletons consist of three major classes of elements that differ in size and in protein composition. Microtubules are the largest type of filament, with a diameter of about 25 nanometers (nm), and they are composed of a protein called tubulin.Actin filaments are the smallest type, with a diameter of only about 6 nm, and they are made of a protein called actin.ll cytoskeletons consist of three major classes of elements that differ in size and in protein composition.
