      Background InformationTubulin is one of several members of a small family of globular proteins which polymerize to form cytoskeletal structures called microtubules. The most common members of the tubulin family are α-tubulin and β-tubulin. Tubulin dimers, typically composed of α- and β-tubulin subunits, assemble onto microtubules forming large polymers. β-III tubulin is a unique microtubule subunit that is found expressed almost exclusively in neurons. Due to the unique expression pattern of β-III tubulin it is often utilized as a marker to identify neuronal cells from other brain cells such as glia which do not express it. β-III tubulin also serves as a cytoarchitectural marker since it is primarily found within neurite extensions.

      Antibody TypeMonoclonal Antibody
      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a class III member of the beta tubulin protein family. Beta tubulins are one of two core protein families (alpha and beta tubulins) that heterodimerize and assemble to form microtubules. This protein is primarily expressed in neurons and may be involved in neurogenesis and axon guidance and maintenance. Mutations in this gene are the cause of congenital fibrosis of the extraocular muscles type 3. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 6. [provided by RefSeq, Oct 2010].

      UniProt Number
      UniProt SummaryFUNCTION: Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha-chain. TUBB3 plays a critical role in proper axon guidance and mantainance.
      SUBUNIT STRUCTURE: Dimer of alpha and beta chains.
      SUBCELLULAR LOCATION: Cytoplasm › cytoskeleton.
      TISSUE SPECIFICITY: Expression is primarily restricted to central and peripheral nervous system. Greatly increased expression in most cancerous tissues.
      DOMAIN: The highly acidic C-terminal region may bind cations such as calcium.
      PTM: Some glutamate residues at the C-terminus are polyglutamylated. This modification occurs exclusively on glutamate residues and results in polyglutamate chains on the gamma-carboxyl group. Also monoglycylated but not polyglycylated due to the absence of functional TTLL10 in human. Monoglycylation is mainly limited to tubulin incorporated into axonemes (cilia and flagella) whereas glutamylation is prevalent in neuronal cells, centrioles, axonemes, and the mitotic spindle. Both modifications can coexist on the same protein on adjacent residues, and lowering glycylation levels increases polyglutamylation, and reciprocally. The precise function of such modifications is still unclear but they regulate the assembly and dynamics of axonemal microtubules Probable.
      Phosphorylated on Ser-172 by CDK1 during the cell cycle, from metaphase to telophase, but not in interphase. This phosphorylation inhibits tubulin incorporation into microtubules.
      INVOLVEMENT IN DISEASE: Defects in TUBB3 are the cause of congenital fibrosis of extraocular muscles type 3A (CFEOM3A) [MIM:600638]. A congenital ocular motility disorder marked by restrictive ophthalmoplegia affecting extraocular muscles innervated by the oculomotor and/or trochlear nerves. It is clinically characterized by anchoring of the eyes in downward gaze, ptosis, and backward tilt of the head. Congenital fibrosis of extraocular muscles type 3 presents as a non-progressive, autosomal dominant disorder with variable expression. Patients may be bilaterally or unilaterally affected, and their oculo-motility defects range from complete ophthalmoplegia (with the eyes fixed in a hypo- and exotropic position), to mild asymptomatic restrictions of ocular movement. Ptosis, refractive error, amblyopia, and compensatory head positions are associated with the more severe forms of the disorder. In some cases the ocular phenotype is accompanied by additional features including developmental delay, corpus callosum agenesis, basal ganglia dysmorphism, facial weakness, polyneuropathy.
      SEQUENCE SIMILARITIES: Belongs to the tubulin family.
