WebThe cytoskeleton of eukaryotic cells is composed of three major protein families that form filamentous structures running throughout the cell, ie microfilaments consisting of different actin isoforms, microtubules made of α- and β-tubulin, and the intermediate filaments, together with their associated molecular motors and regulatory protein complexes. WebThe cytoskeleton is a structure that runs throughout the cytoplasm of a cell and controls a variety of processes. It aids in the maintenance of the cell’s shape and provides support. A variety of cellular organelles are held in place by the cytoskeleton. It aids in the development of vacuoles. The cytoskeleton is a dynamic structure that can ...
