Actin's primary role in the cell is to form linear polymers called microfilaments that serve various functions in the cell's structure, trafficking networks, migration, and replication. The multifaceted role of actin relies on a few of the microfilaments' properties: First, the formation of actin filaments is reversible, and their function often involves undergoing rapid polymerization and depoly… WebMicrotubules are the largest type of filament, with a diameter of about 25 nanometers (nm), and they are composed of a protein called tubulin .
