Microtubules are structures found in animal cells and are made up of tubulin protein building blocks. Molecular motor proteins, kinesins, move in one direction along microtubules transporting other proteins. In this image a fictional protein, shaped like a excavator with a wrecking ball, is being dragged to the end of the microtubule where it dismantles the tube structure.
