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.
Spindle microtubules attach to a specific protein complex called the kinetochore, which is in the centromere area near the center of each chromosome. Other microtubules attach to the chromosome arms or to the other end of the cell.The chromosomes can also create microtubules, as can the spindle itself. The spindle and chromosomal microtubule arrangement is a macromolecular machine that is intricate and dynamic.omponents. The spindle microtubules are protein fibers made up of as many as 45 different proteins that grow from the centrioles. They form a polymer, which is a large molecule made up of many similar molecules linked together.
