Tubulin

Tubulin (TUB) is a constituent of microtubules in eukaryotes. Microtubules are assembled from dimers of α-tubulin (TUBA) and β-tubulin (TUBB) bound to GTP. See also Beta tubulin. γ-tubulin (TUBG) is part of the nucleation of microtubules. Human TUB contains several numbered subtypes. FtsZ (Filamenting temperature-sensitive mutant Z) is a prokaryotic homologue of TUB.
