2. The function of cytoskeleton in general The elements that make up the cytoskeleton function in a number of interrelated activties 1)As a scaffold and structural supports within cell They help formation and maintain the dynamic shape of the cell. For example, the shape of mammalian. erythrocyte is maintained by the spectrin-actin cytoskeleton As an internal framework responsible for positioning and organization of the various organelles within the cell. which leads differentiated cells possessing special morphological structure, and as sites for anchoring messenger RNAs and some proteins with bi coreaction activities (including some enzymes) and facilitating protein translation and order biochemical reaction
