The tubulin protein is a major target of drug molecules, and consequently, tubulin inhibitors have attracted great attention as antimitotic antitumor agents for chemotherapeutic use. The effects on tubulin messenger RNA levels and tubulin protein synthesis of microtubule-depolymerizing drugs and of direct microinjection of cells with tubulin suggest that non-polymerized tubulin represses its own synthesis.

There are three classes of the ~50 kDa tubulin proteins: alpha, beta, and gamma. The alpha and beta tubulins form a heterodimer that polymerize into the cylindrical microtubule fibers. Both alpha and beta tubulin bind GTP; however, only beta tubulin hydrolyzes GTP to GDP. This hydrolysis is a process that is linked to tubulin polymerization and microtubule formation. The alpha tubulin isoform can be modified by the addition of a C-terminal tyrosine residue, and this modification may influence polymerization rates. The gamma tubulin isoform is localized to centrosomes which compose the heart of the microtubule organizing center from which microtubule fibers emanate.
