General description

Tubulin α 1a (TUBA1A) is a member of α-tubulin gene family. It is encoded by the gene mapped to human chromosome 12q13.12. Tubulin α 1a is a vital structural subunit of microtubules that are temporarily expressed in almost all post-mitotic neurons during neuronal development.
The encoded protein structure contains core of two β-sheets enclosed by α-helices. TUBA1A is characterized with an amino-terminal domain with the guanine nucleotide-binding region, an intermediate domain associated with interprotofilament lateral contacts and the modulation of tubulin curvature, and a carboxy-terminal domain that contains region involved in interacting with microtubule-associated proteins (MAPs) and molecular motors, such as kinesins and dynein.

Antigen Background

Tubulin is a cylindrical, filamentous structure is present inalmost all eukaryotic cells.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.


Anti-α-Tubulin antibody, Mouse monoclonal has been used in western blotting.

Biochem/physiol Actions

Gene mutation of tubulin α-1A (TUBA1A) is observed in perisylvian asymmetrical polymicrogyria, polymicrogyria-like cortical dysplasia, and microlissencephaly in foetal cases. Alteration in the expression of the gene impairs neural migration and causes lissencephaly (LIS).
