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 cytoskeletal structural components found in the cells of vertebrates, and many invertebrates. Homologues of the IF protein have been noted in an invertebrate, the cephalochordate Branchiostoma. Intermediate filaments are composed of a family of related proteins sharing common structural and sequence features. Initially designated 'intermediate' because their average diameter is between those of narrower microfilaments and wider myosin filaments found in

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 a main integral part of the cytoskeletal system and bear much of the tension inside the cell. They are smaller than microtubules but larger than microfilaments. Intermediate filaments are a very broad class of fibrous proteins that play an important role as both structural and functional elements of the cytoskeleton. Ranging in size from 8 to 12 nanometers (in diameter; see Figure 1), intermediate filaments function as tension-bearing elements to help maintain cell shape and rigidity, and serve to anchor in place several organelles, including the nucleus and desmosomes. The primary function of intermediate filaments is to create cell cohesion and prevent the acute fracture of epithelial cell sheets under tension.

Intermediate filaments function

av N Garis · 2009 · Citerat av 1 — mushy zone is modeled as a function of the liquid fraction FL. In a mushy zone, face particles (arbitrary shape big particles, filaments-like middle size particles,. Intermediera filament är cellskelettets starkaste beståndsdelar, vars uppgift är att stärka cellskelettet, så det tål att sträckas. Celler som utsätts för stor mekanisk NARCOSIS. A narcotic substance is one that depresses the normal function of the represents one example where the toxicity is due to the intermediate or metabolite filaments of nearly uniform diameter produced by extruding molten glass.

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.

The function of these structures and the requirement for different types of intermediate The best evidence for intermediate filament function comes from observing the consequences of mutation and mis-expression, primarily in human tissues. av M Ding · 2000 · Citerat av 1 — Title: Role of intermediate filaments and expression of GFAP and S-100 in astrocytes. Authors: Ding, Mei 1965-. Issue Date: 2000.
