The cytoskeleton is a dynamic fibrous network composed of microfilaments, microtubules, and intermediate filaments, mainly consisting of actin, tubulin, and different types of intermediate filament proteins. The cytoskeleton not only maintains cell morphology, cell polarity, and intracellular ...
Microfilaments are mainly formed by the polymerization of actin and are an important component of the cytoskeleton. They participate in the maintenance of cell morphology, adhesion and migration, cytokinesis, endocytic transport, stress fiber formation, and the establishment of cell polarity.
