Intermediate filaments are present in most animal cells. They are composed of more than 50 proteins which are expressed in a cell‐type specific manner. Their diameter is about 10 nm and thus between those of the larger microtubules and the smaller F‐actin. They form scaffolds and networks in the cyto‐ and nucleoplasm. Cytoskeleton

What does intermediate-filament mean? Any of a group of protein filaments that are a component of the cytoskeleton in animal cells, are composed of a variety

Intermediate filaments are composed of

Intermediate filaments have a twisted, rope-like structure that provides mechanical support to the cell. Cells that are subject to mechanical stress, such as hair and skin cells, contain a higher amount of intermediate filaments compared to other cell types. Most intermediate filament proteins assemble under suitable conditions (see later) to form uniform 8-12 nm wide filaments. However, several types of IFPs are obligate heteropolymers, they require a heterologous IFP to be present in order to assemble in the co-polymer form (for example: NF-M or NF-H).

Glial cells produce a special type of intermediate filaments known as glial intermediate filaments, which differ structurally from neurofilaments in that they are composed of a single 51 kDa protein and have different physicochemical properties. Intermediate filament class V: nuclear lamina filaments

Intermediate filaments are found only in complex multicellular organisms. They are encoded by a large number of different genes and can be grouped into families based on their amino acid sequences. Cells in different tissues of the body express one or another of these genes at different times.

As we just stated, intermediate filaments are cytoskeletal components of cells that are mid-sized of the three Intermediate filaments are not well-characterized in plants to date. In animals, these filaments are formed of polymers of keratin, vimentin, or lamin. In plants, Animal cells have a third element, intermediate filaments. All three of these cytoskeletal elements are long chains, or polymers, made up of protein subunits. The thin filament also contains two other proteins called troponin and tropomyosin, which are involved in muscle contraction. The thick filament consists of a To date, the functions of most neural intermediate filament (IF) proteins have remained elusive. Peripherin is a type III intermediate filament (IF) protein that is Intermediate filaments are composed of a family of related proteins sharing common structural and sequence features.

This structure consists of a structurally conserved central “rod” domain, composed of heptad repeats that are required for the coiled-coil interactions involved in the assembly of IFs; the rod domain is flanked on both ends by non-helical N- (“head”) and C-terminal (“tail”) domains. Intracellular protein filaments intermediate in size between actin filaments and microtubules are composed of a variety of tissue specific proteins. The sequence conservation of the coiled-coil alpha-helical structure responsible for polymerization into individual 10 nm filaments defines a large gene family. Intermediate filaments, Type-IV, heteropolymer intermediate filaments that are composed of three neurofilament subunits (NF-L, NF-M and NF-H), which are expressed mainly in neurons.

Intermediate filament class V: nuclear lamina filaments

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). 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 implications of these findings are discussed for three classes of model previously proposed for the structure of intermediate filaments. Intermediate filaments were originally named because with diameters between 8 and 10 nm, they are intermediate in size between the microtubules (at 25 nm) and the microfilaments at 7 nm. These intermediate filaments are composed of a number of different proteins. They play some structural or tension-bearing role. Intermediate filaments constitute the third component of the cellular skeleton. Unlike actin and microtubule cytoskeletons, the intermediate filaments are composed of a wide variety of structurally related proteins showing distinct expression patterns in tissues and cell types.
