In some cells, there are as many as ten times the number of intermediate filaments as there are other microfilaments or Difference Between Intermediate Filaments and Microfilaments is that Intermediate filaments are the structures that form a network around the nucleus and extend to the periphery of the cell. While Microfilaments are long and fine thread­like structures with a diameter of about 3 to 6 nm. These filaments are made up of non-tubular contractile proteins called actin and myosin. 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.

Difference Between Intermediate Filaments and Microfilaments is that Intermediate filaments are the structures that form a network around the nucleus and extend to the periphery of the cell.

More than 70 genes, partitioned in six major classes, encode IF-forming proteins and are regulated in a tissue-specific and differentiation-dependent fashion. “Intermediate filaments” is actually a generic name for a family of proteins (grouped into 6 classes based on sequence and biochemical structure) that serve similar functions in protecting and shaping the cell or its components.

Intermediate filaments

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).

This review presents the current knowledge of the basic biology of intermediate filaments, including their phylogenetic distribution and their distribution within mammalian cells.

Intermediate filaments

How New … 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 Filament Proteins (IFPs) acquired their name from their filamentous form.

Some intermediate filaments are closely linked to specific cell types. Neurofilaments, as the name suggest, are found exclusively in neurons. Muscle cells contain a type called desmin filaments, and keratins are present in the epithelial cells. Other types of intermediate filaments are found more widely distributed in various types of cells.
