As we just stated, intermediate filaments are cytoskeletal components of cells that are mid-sized of the three cytoskeletal fibers. Think of them as the small pickup truck of these fibers. 4 intermediate filament proteins are self-assembling components Biochemical purification of the various IF proteins from tissues and cultured cells revealed that they all can be renatured after purification under chaotropic conditions, and nearly all of them would self-assemble into 10-nm-like filaments ( Steinert et al. 1976 ; Renner et al. 1981 ).

In general, intermediate filaments serve as structural elements, helping cells maintain their shape and integrity. For example, keratin filaments, the intermediate filaments of epithelial cells, which line surfaces of the body, give strength to the cell sheet that covers the surface. Intermediate filaments consist of several intertwined strands of fibrous proteins. Intermediate filaments have no role in cell movement. Their function is purely structural. They bear tension, thus maintaining the shape of the cell, and anchor the nucleus and other organelles in place. I ntermediate filaments (Fig.

However, little information exists on the structure of the IF networks performing these functions. Intermediate filaments function in the maintenance of cell-shape by bearing tension. For example, in our skin cells, the protein keratin is an intermediate filament which provides shape and protection against over-stretching. Intermediate filaments provide scaffolding for the cell and protect it against stress. This comprehensive review points out that there are more than 100 intermediate filament genes and that mutant Intermediate Fibers/Intermediate Filaments (IF) Unlike the other cytoskeleton components, intermediate filaments are made up of a large family of polypeptides. For this reason, there is a wide variety of intermediate filaments in different types of cells. The tight association between protofilaments provide intermediate filaments with a high tensile strength.
1981 ). Intermediate Filaments: Definition, Function & Structure Intermediate filaments, like keratin, support the cell structure and help cushion mechanical stress in areas such as the skin. Intermediate filament (IF) scaffolds facilitate small heat shock protein (sHSP) function, while IF function is sHSP dependent. sHSPs interact with IFs and the importance of this interaction is to maintain the individuality of the IFs and to modulate interfilament interactions both in networks and in assembly intermediates. The most common intermediate filament comprising the cytoskeleton is vimentin, a type III intermediate filament that regulates the F-actin and microtubule filament systems along with cell signaling, motility, structure, and adhesion during interphase and mitosis and whose assembly, disassembly, binding partners (14-3-3 and Beclin 1), and function are regulated by a variety of post
Intermediate fibers are of four types-keratin filaments, neurofibrils, gilal filaments and heterogeneous filaments (Desmin, vimentin, synemin, lamin and keratin filaments). They provide rigidity to the cell and maintain the cell structure.

The function of intermediate filaments is largely mechanical, meaning they provide support for the cell so that other microfilaments can more readily do their transport jobs. Some intermediate filaments are even arranged in a mesh-like pattern to provide for the different support needs of different kinds of cells. Intermediate filaments are therefore found in particularly durable structures such as hair, scales and fingernails. The primary function of intermediate filaments is to create cell cohesion and prevent the acute fracture of epithelial cell sheets under tension.

Intermediate filaments are a main integral part of the cytoskeletal system and bear much of the tension inside the cell.
