Post-translational modification is one of the factors affecting the properties of microtubule polymers. CD BioSciences is committed to developing cutting-edge microtubule post-translational modification detection services, and has established a mature PTMs detection platform to provide high-quality protein modification-related services according to customer needs.
Post-translational Modifications of Microtubules
Microtubules play important roles in many cellular processes, including intracellular transport, cell motility, and chromosome segregation during cell division. In addition, microtubule duplexes or triplexes form scaffolds for cilia, centrioles and basal bodies, respectively. In order to perform such diverse functions, microtubule properties must differ. Post-translational modifications are one of the factors that influence the properties of microtubule protein polymers.

Various Types of PTMs of Microtubules
Post-translational modifications of microtubule proteins provide the material basis for both the diversification of microtubule function and the mechanisms of multiple physiological environmental regulation. Such post-translational modifications of microtubules are essential for the regulation of microtubule properties and functions.
- Polyamidations: Polyaminylated microtubule is abundant in the axons of neuronal cells, but only present at low levels in non-neuronal cells. In vitro, both free microtubule heterodimers and microtubule heterodimers bound to microtubules can be modified by transglutaminase.
- Acetylation: Acetylation is a highly evolutionarily conserved microtubule protein modification in which acetylation begins at the microtubule ends during microtubule growth and the acetylated fragment expands with microtubule elongation and enzymatic diffusion.
- Methylation: In mitotic cells, α-tubulin of the central spindle, but not astral microtubules, is modified by trimethylation at the K40 by SET-domain-containing 2 (SETD2) methyltransferase.
- Phosphorylation: Numerous studies have shown that both α- and β-microtubule can be phosphorylated on serine, threonine, and tyrosine residues. However, the physiological significance of microtubule phosphorylation has rarely been elucidated.
- Tyrosination: A tyrosine residue is the most frequent gene encoded final amino acid residue on the α-tubulin C-terminal end. This residue can be removed from α-tubulin incorporated into microtubules by an unknown carboxypeptidase, leading to the formation of so-called Glu-tubulin.
- Glutamylation: Glycylation and glutamylation are polymeric modifications that consist of one or more glycyl or glutamyl residues, respectively, ligated to the glutamic acid residues within the C-terminal tail of both α- and β-tubulin.
- Glycosylation: Glycosylation is one of the least studied post-translational modifications of microtubule proteins. Only microtubules of cilia and flagella are glycosylated, and glycosylation may be essential for cilia and flagella to function properly.
