Intermediate filaments (IFs) are cytoskeletal components found in the cells of many animal species. They are composed of a family of related proteins sharing common structural and sequence features.ntermediate filaments (IFs) are cytoskeletal components found in the cells of many animal species. They are composed of a family of related proteins sharing common structural and sequence features.
For example, most animal epithelial cells contain keratins, a diverse family of intermediate filaments consisting of more than 50 members, while mesenchymal and muscle cells are rich in the fibrous proteins, vimentin and desmin, respectively.nother highly specialized class of intermediate filaments are the nuclear lamins, which constitute the fibrous protein network that lines the inside of the nuclear membrane, as discussed above.
