Intermediate filaments -LRB- IFs -RRB- are cytoskeletal components found in the cells of vertebrate animal species , and perhaps also in other animals , fungi , plants , and unicellular organisms .. cytoskeletal. cytoskeleton. vertebrate. vertebrate. animal. metazoa. They are composed of a family of related proteins sharing common structural and sequence features .. Initially designated ` intermediate ' because their average diameter -LRB- 10 nm -RRB- is between those of narrower microfilaments -LRB- actin -RRB- and wider myosin filaments found in muscle cells , the diameter of Intermediate filaments is now commonly compared to actin microfilaments -LRB- 7 nm -RRB- and microtubules -LRB- 25 nm -RRB- .. myosin. myosin. actin. actin. Most types of intermediate filaments are cytoplasmic , but one type , the lamins , are nuclear .. lamins. #Type V - Nuclear Lamins
