General description

α-tubulin, also called as tubulin α 4a (TUBA4A), is mapped to human chromosome 2q35. The gene codes for a member of the α-tubulin family containing 448 amino acids. TUBA4A belongs to the subfamily of tubulin, which is the major building block of microtubules. α-subunit of tubulin has molecular weight of 50,000.

Specificity

The antibody recognizes an epitope located on the α3 isoform of Chlamydomonas axonemal α-tubulin, within four residues of Lys-40 when this amino acid is acetylated. A sequence very similar to the one detected by the antibody in Chlamydomonas is found in the majority of α-tubulins, but the corresponding region is markedly divergent in some α-tubulin isoforms from chicken, Drosophila and yeast. The antibody has been used to detect acetylated α-tubulins in several organisms. Occasionally, the epitope recognized by the antibody may be absent or masked as it is in the kangaroo rat epithelial-like cell line PtK2.

Immunogen

acetylated α-tubulin from the outer arm of sea urchin sperm axonemes.

Application

Monoclonal Anti-Tubulin, Acetylated antibody produced in mouse has been used in following studies:
  • immunofluorescence.
  • western blotting.
  • immunocytochemistry.
  • immunohistochemistry.

Biochem/physiol Actions

Acetylated tubulin is associated with axoneme assembly in a variety of organisms. Acetylated tubulin might play a crucial role in the differentiation of microtubule structure and function. Post translational modification of α-tubulin i.e. the reversible addition of an acetyl group to Lys40, by specific acetylase, results in acetylated tubulin.

Antibodies to Tubulins, including Centrosome-Associated ε-Tubulin

Microtubules of the eukaryotic cytoskeleton are composed of a heterodimer of α- and β-tubulin. In addition to α-and β-tubulin, several other tubulins have been identified, bringing the number of distinct tubulin classes to seven.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
