General description

Microtubules are heterodimeric proteins that comprise of α- and β-tubulins. β-tubulins have four different isotypes in brain cells, ranging from β I to β IV . Anti-tubulin antibodies are useful to study the localization of tubulin proteins. Monoclonal Anti-β-Tubulin IV antibody is specific for epitope located in the C-terminal sequence of β-tubulin isotype IV in humans, bovines, hamsters, rats, mice and chickens. The product does not react with other tubulin isotypes.

β-Tubulin IV codes for β-tubulin 4A (TUBB4A). TUBB4A is expressed in the central nervous system by oligodendrocytes. It is located on human chromosome 19p13.3.


synthetic peptide corresponding to the C-terminal sequence of β-tubulin isotype IV, conjugated to BSA.

Biochem/physiol Actions

β-Tubulin IV creates the oligodendrocyte microtubule network, that helps in the transport of myelin proteins, lipids and RNA at the time of myelination. It participates in the generation of early fibrotic stages. TUBB4 plays a major role in the transport and proper localization of N-cadherin within the plasma membrane.

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 dist...
