The cytoskeleton (literally, "cell skeleton") is a network of filaments that supports the plasma membrane, gives the cell an overall shape, aids in the correct positioning of organelles, provides tracks for the transport of vesicles, and (in many cell types) allows the cell to move. In such cases, the RNA plays the role of the scaffold for one or more RNA-binding protein, which is in direct contact with chromatin.
