Alpha-Tubulin acetyltransferase (alphaTAT1) is the major α-tubulin lysine-40 (K40) acetyltransferase in mammals, nematodes, and protozoa, and its activity plays a conserved role in several microtubule-based processes.|The tubulin subunits of microtubules are acetylated, and lysine-40 (K40) of the alpha-tubulin subunit has been identified as an important conserved site of microtubule acetylation (6–8). This modification is considered a hallmark of stable, long-lived microtubules |

Here we integrate a computational model for microtubule assembly with nanometer-scale fluorescence microscopy measurements to identify the kinetic and thermodynamic basis of kinetic stabilization by the MTAs paclitaxel, an assembly promoter, and vinblastine, a disassembly promoter. We identify two distinct modes of kinetic stabilization in live cells, one that truly suppresses on-off kinetics, characteristic of vinblastine, and the other a "pseudo" kinetic stabilization, characteristic of paclitaxel, that nearly eliminates the energy difference between the GTP- and GDP-tubulin thermodynamic states. By either mechanism, the main effect of both MTAs is to effectively stabilize the microtubule against disassembly in the absence of a robust GTP cap. |

The complex marine natural product halichondrin B was compared with NSC 707389 (E7389), a structurally simplified, synthetic macrocyclic ketone analog, which has been selected for clinical trials in human patients. NSC 707389 was invariably more potent than halichondrin B in its interactions with tubulin. Both compounds inhibited tubulin assembly, inhibited nucleotide exchange on beta-tubulin, and were noncompetitive inhibitors of the binding of radiolabeled vinblastine and dolastatin 10 to tubulin. |

We show here that Elongator regulates corticogenesis because an acute disruption of its activity in dorsal progenitors results in radial migration delays and defective terminal branching of projection neurons that come with a reduction in α-tubulin acetylation. Importantly, this complex interacts with the microtubule cytoskeleton, where Elp3 may directly acetylate α-tubulin, a posttranslational modification known to regulate the intracellular trafficking that is critical for cell shape remodeling during migration and terminal branching. |

Tubulin exists in the cell as dimers of α and β subunits, which complexes with a variety of regulatory proteins. There is a dynamic equilibrium between free and polymerized tubulin causing a state called "dynamic instability," which is a target of anticancer drugs, which inhibit tubulin through polymerization (taxanes, epothilones) or depolymerization (vinca alkaloids). Docetaxel-based therapy was the first such treatment to demonstrate a survival benefit in men with castration-resistant prostate cancer. |
