FunctionTubulin (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[1]. Human TUB contains several numbered subtypes. FtsZ (Filamenting temperature-sensitive mutant Z) is a prokaryotic homologue of TUB[2]. See Cell division protein and Beta tubulin.
RelevanceThe chemotherapeutic drug Taxol interacts with TUBB. See Molecular Playground/Taxol. TUBA and TUBB expression in polyps of invasive colon cancer is different from normal[3].
DiseaseMutations in TUBB underlie a large spectrum of neuronal migration disorders[4].
