The protein tubulin is the principal constituent of microtubules, whose dynamic behaviour allows them to perform a vital role in various forms of cell motility. Found in almost all types of eukaryotic cell, microtubules are an essential component of cell division, provide tracks for the transport of cellular organelles and vesicles and are responsible for the relative positioning of cellular compartments.
