Vimentin is an intermediate filamentous cytosketetal protein found in cells of mesenchymal origin. Vimentin typically exists as a coiled-coil dimer that interacts with another dimers to form a tetrameric complex that forms cytoskeletal protein sheets. Vimentin intermediate filaments are believed to be important cytosolic structures responsible for positioning organelles. It has been found to interact with the Golgi, ER, mitochondria and nucleus.
