Target Information

Beta tubulins are one of two core protein families (alpha and beta tubulins) that heterodimerize and assemble 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 associated with 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, although the precise function of such modifications remains unclear. Tubulin is phosphorylated on Ser-172 by CDK1 during cell cycle progression, and this phosphorylation inhibits tubulin incorporation into microtubules.

Microtubules, the major cytoskeletal elements found in all eukaryotic cells, consist of tubulin dimers (alpha and beta subunits, ~55 kDa each). They play key roles in chromosome segregation during mitosis, intracellular transport, ciliary and flagellar movement, and structural support of the cytoskeleton. Because beta-tubulin is ubiquitously expressed, it is commonly used as a loading control in protein detection assays such as Western blotting.
