Added to this they also help in determining the shape of the cell, movement of the cell, and transportation of the cytoskeleton structures play an very important role in the direction of cell division and differentiation. Many of the components also help in chromosomal movement and cytokinesis.
Abstract. The mitotic spindle, a microtubuleâbased structure, is required for chromosome segregation during cell division. Motor proteins are molecular machines that utilise the energy of adenosine triphosphate (ATP) hydrolysis to move along microtubules.uring cell division, motor proteins are required for spindle formation, chromosome alignment and segregation. Thus, mitotic motor proteins are required for the cell to avoid aneuploidy, a hallmark of cancer.
