Microtubules are assembled from α-tubulin–β-tubulin dimers, which form hollow tubes composed of 13 protofilaments. [2] [3] Both α and β tubulins have a mass of around 50 kDa and are thus in a similar range compared to actin (with a mass of ~42 kDa). In contrast, tubulin polymers (microtubules) tend to be much bigger than actin filaments due to their cylindrical nature. Tubulin was long thought to be specific to eukaryotes.
