In epithelium, for instance, intermediate filaments provide mechanical support for the plasma membrane where it comes into contact with other cells or with the extracellular matrix. Intermediate filaments Intermediate filaments have an average diameter of 10 nanometers, which is between that of 7 nm actin (microfilaments), and that of 25 nm microtubules, although they were initially designated ‘intermediate’ because their average diameter is between those of narrower microfilaments (actin) and wider myosin filaments found in muscle cells. Three filamentous systems make up the cytoskeleton of cells. These are microfilaments, microtubules and the intermediate filaments. Sixty-five homologous proteins with the ability to form 10 nm Intermediate filament (IF) proteins belong to a large and diverse gene family with broad representation in vertebrate tissues.

The intermediate filaments of the eukaryotic cytoskeleton , which the cytokeratins are one of its three components, have been probed to associate also with the ankyrin and spectrin complex protein network that underlies the cell membrane. Intermediate filaments are one of the three types of cytoskeletons in the cell.

Eukaryotic cells contain three main kinds of cytoskeletal filaments, which are microfilaments, intermediate filaments, and microtubules. The cytoskeleton provides 

Intermediate filaments are important components of the cell's cytoskeletal system. They may stabilize organelles, like the nucleus, or they may be involved in specialized junctions. They are distinguished from "thin filaments" by their size (8-10 nm) and the fact that thin filaments are obviously motile. Intermediate filaments have long been considered mechanical components of the cell that provide resistance to deformation stress.

The components and structure of intermediate filaments vary between different cell types. While they extend through the whole cytosol, immunofluorescent staining of intermediate filaments is sometimes more concentrated in the perinuclear region.

Their main role lies in providing mechanical support to the cell, as well as participating in organization of the chromatin in the cell nucleus. The latter is achieved by anchoring the chromatin to the nuclear lamina that lines the inner part of the nuclear membrane. Intermediate filaments are about 10 nm in diameter with wavy profiles in electron micrographs of thin sections of cells (Fig.
