What are the 2 major cytoskeletal classes that participate in cell division? What are their function? Solution We have to know that cytoskeletal classes that participate in cell division,the cytoskeleton is a structure that helps cells maintain their shape and internal organization also provides mechanical support that enables cells to carry out essential functions like division and movement.Cytoskeleton of eukaryotic cells is made of filamentous proteins and it provides mechanical support to the cell and its cytoplasmic constituents. Actin filaments and microtubules, intermediate filaments are constructed from a number of different subunit proteins.They are composed of proteins that have the unique property of being able to self-assemble into a filamentous network.The proteins that make each of the three different filament systems assemble into only the structure characteristic of that filament..
