Specifically acetylates 'Lys-40' in alpha-tubulin on the lumenal side of microtubules. Promotes microtubule destabilization and accelerates microtubule dynamics; this activity may be independent of acetylation activity. Acetylates alpha-tubulin with a slow enzymatic rate, due to a catalytic site that is not optimized for acetyl transfer. Enters the microtubule through each end and diffuses quickly throughout the lumen of microtubules. Acetylates only long/old microtubules because of its slow acetylation rate since it does not have time to act on dynamically unstable microtubules before the enzyme is released. Required for normal sperm flagellar function. Promotes directional cell locomotion and chemotaxis, through AP2A2-dependent acetylation of alpha-tubulin at clathrin-coated pits that are concentrated at the leading edge of migrating cells. May facilitate primary cilium assembly.

Results suggest that lithium chloride (LiCl) treatments activate alpha-tubulin N-acetyltransferase 1 (alphaTAT1) by the inhibition of glycogen synthase kinase 3 beta (GSK-3beta) and promote the alpha-tubulin acetylation, and then elongate the primary cilia.PMID:24760594
Data suggest that invariant residues Arg132 and Ser160 in catalytic domain of ATAT1 participate in stable interaction with CoA and acetyl-CoA; ATAT1 with mutation at either residue exhibits much faster intracellular degradation.PMID:25602620

Mechanistic underpinnings for TAT activity and its preference for microtubules with slow turnover; cocrystal structures constrain TAT action to the microtubule lumen with Lys40 engaged in a suboptimal active site; despite the confined location of Lys40, TAT efficiently scans the microtubule bidirectionally and acetylates stochastically without preference for ends.PMID:24906155
