Intermediate filament s are one component of the cytoskeleton-important structural components of living cells. Their size is intermediate between that of microfilament s and microtubules. They are assembled from several different proteins.
Intermediate filaments are one of three types of cytoskeletal elements. The other two are thin filaments (actin) and microtubules. Frequently the three components work together to enhance both structural integrity, cell shape, and cell and organelle motility. Intermediate filaments are stable, durable.
