English: A single, large microtubule (blue) is shown, flanked by several arching actin filaments (also blue). A single intermediate filament (blue) is also shown, which transverses over the microtubule and actin filaments. Two thin plectin side chains (blue) are shown, which connect the intermediate filament to flanking actin filaments. Ribosome structures (magenta) are shown translating mRNA into new polypeptide chains. Other cytosolic proteins are shown throughout the image (purple, dark blue).
