... - 1TUB (pig). Tubulin is a globular (roughly spherical) protein that makes up microtubules in the cytoskeleton. Cilia, flagella, and the mitotic spindle are made of microtubules; many vesicles move along microtubules. Tubulin molecules occur as dimers containing one alpha-tubulin (1TUB_A) and one beta...
