Technical Data
Tubulin, alpha, acetyl (Lys40) (Alpha Tubulin, Tubulin alpha Ubiquitous, H2-Alpha, K-alpha-1, TUBA3, Tubulin alpha 1 Chain, TUBA1, TUBA1A, Tubulin K alpha 1)
The cytoskeleton consists of three types of cytosolic fibers: microtubules, microfilaments (actin filaments), and intermediate filaments. Globular tubulin subunits comprise the microtubule building block, with alpha/beta-tubulin heterodimers forming the tubulin subunit common to all eukaryotic cells. Gamma-tubulin is necessary to nucleate polymerization of tubulin subunits to form microtubule polymers. Many cell movements are mediated by microtubule action, including the beating of cilia and flagella, cytoplasmic transport of membrane vesicles, chromosome alignment during meiosis/mitosis, and nerve-cell axon migration. These movements result from competi-tive microtubule polymerization and depolymerization or through the actions of microtubule motor proteins (1). The Elongator complex catalytic subunit (Elp3) acetylates alpha-tubulin at Lys40 while the histone deacetylase HDAC6 functions as a tubulin deacetylase. This post-transcriptional modification may be required for dynamic cell shape remod-eling, cell motility, tubulin stability and terminal branching of cortical neurons (2,3).
