I ntermediate filaments (Fig. 35-1) are strong but flexible polymers that provide mechanical support for cells ranging from bacteria to human tissues. These filaments were named intermediate because their diameter of about 10 nm is intermediate between the diameters of the thick and thin filaments in striated muscles (see Figs. 39-3 and 39-8).

Thus, the idea of IFs are static had to be reassessed, and more studies determined that they were indeed highly motile and involved in numerous other functions,

These filaments were named intermediate because their diameter of about 10 nm is intermediate between the diameters of the thick and thin filaments in striated muscles (see Figs. 39-3 and 39-8). 2007-06-10 · The best evidence for intermediate filament function comes from observing the consequences of mutation and mis-expression, primarily in human tissues.

Initially designated 'intermediate' because their average diameter is between those of narrower microfilaments and wider myosin filaments found in 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 (IFs) are the most enigmatic component of the eukaryotic cytoskeleton. IFs are often a major component of the cell and are most prominent in the cells of vertebrates.

This lecture explains about the intermediate filaments assembly and structure and function of intermediate filament.http://shomusbiology.com/Download the stu intermediate filaments 1. IFs Summary (LODISH BK. M.B) The association of intermediate filaments with the nuclear and plasma membranes suggests that their principal function is structural.

The tight association between protofilaments provide intermediate filaments with a high tensile strength. This makes them the most stable component of the cytoskeleton. Intermediate filaments are therefore found in particularly durable structures such as hair, scales and fingernails.

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.

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.

What is the most important function of intermediate filaments? To provide mechanical support for plasma membrane where it comes into contact with other cells or extracellular matrix describe how intermediate filaments are arranged in the cell Functions of intermediate filaments Intermediate filaments help to maintain the shape of the cell. These filaments also connect the adjacent cells through desmosomes. Se hela listan på proteinatlas.org Intermediate filament (IF) constitutes an important cytoskeletal component in nearly all the vertebrate cells.
