General description

Human α tubulin acetyltransferase 1, or ATAT1, (GenBank Accession No. NM_001031722 (var1)), amino acids 2 – 224 with N-terminal GST-tag, MW=52 kDa, expressed in an E. coli expression system.
The αTAT1 (α tubulin acetyltransferase 1) protein sequence of αTAT1 is highly conserved among eukaryotes. αTAT1 is a member of Gcn5 (general control non-depressible 5)-related N-acetyltransferase superfamily and is mostly present in ciliated organisms. It has also been identified in Tetrahymena, nematodes, zebrafish and mice.

Biochem/physiol Actions

ATAT1 (α tubulin acetyltransferase 1) catalyses the acetylation of lysine 40 of α-tubulin and microtubule. ATAT1 expression is essential for microtubule stabilization and mediates cilium formation. Upart from acetylation, αTAT1 interacts with doublecortin (a microtubule associated protein) to degrade microtubules that are not aligned with acetyltransferase activity. αTAT1 regulates the Wnt1 signalling pathway via β-catenin and promotes tumorigenesis. Overexpression of the ATAT1 gene is observed in colon cancer and is known to contribute to its progression.

An assay for alpha-tubulin acetyltransferase (TAT) activity based on affinity isolation of labeled acetylated alpha-tubulin was developed for use with crude subcellular fractions. Microtubules were polymerized and immobilized on an anti-alpha-tubulin-agarose and then incubated with the subcellular fraction and [3H]acetyl-coenzyme
