Target Information

Beta tubulins are one of two core protein families (alpha and beta tubulins) that heterodimerize to form microtubules. Beta-III tubulin is primarily expressed in neurons and may be involved in neurogenesis, axon guidance, and maintenance. Mutations in the beta tubulin gene are linked to congenital fibrosis of the extraocular muscles type 3. Beta-III tubulin is also detected in Sertoli cells of the testis and transiently in non-neuronal embryonic tissues.

Glutamate residues at the C-terminus of beta III tubulin can be glutamylated, though the precise function of this modification remains unclear. Tubulin is phosphorylated on Ser-172 by CDK1 during cell cycle progression, inhibiting its incorporation into microtubules.

Microtubules, composed of alpha and beta tubulin dimers (~55 kDa each), are essential cytoskeletal elements found in all eukaryotic cells. They play critical roles in chromosome segregation, intracellular transport, ciliary and flagellar movement, and maintaining cellular structure. Because beta-tubulin is ubiquitously expressed, it is commonly used as a loading control in protein detection assays such as Western blotting.
