Microtubule play important roles in cell division, intracellular transport, cell movement and in the maintenance of cell structure. Microtubules(MTs) are polymers of dimeric alpha and beta tubulins. They are one of the cytoskeletal elements. They provide rigidity to the cell thereby maintaining its shape.
Microtubules are cylindrical tubes, 20-25 nm in diameter. They are composed of subunits of the protein tubulin--these subunits are termed alpha and beta. Microtubules act as a scaffold to determine cell shape, and provide a set of tracks for cell organelles and vesicles to move on.
