General description

γ-Tubulin, mapped on human chromosome 17q21.2, codes for a member of the tubulin family. It is localized to the microtubule organizing centres. γ-Tubulin consists of two isoforms tubulin γ 1 (TUBG1) and tubulin γ 2 (TUBG2) with 97.3% amino acid identity. In addition to these two isoforms, γ-tubulin pseudogene (TUBG1P) is also been identified on human chromosome 17. Human TUBG1 and TUBG2 transcripts are widely expressed in preimplantation embryos and the brain, respectively. γ-tubulin is a component of γ-tubulin ring complex (γ-TuRC), which has roughly the same diameter as a microtubule.

Specificity

The antibody recognizes an epitope located within the N-terminal region of γ-tubulin.

Immunogen

synthetic γ-tubulin peptide, conjugated to KLH

Application

Monoclonal Anti-γ-Tubulin antibody produced in mouse has been used in following studies:
  • Western blot analysis
  • Immunohistochemistry
  • Immunocytology

Biochem/physiol Actions

γ-Tubulin nucleates microtubule assembly throughout the mammalian cell cycle in vivo. In Aspergillus nidulans, γ-tubulin facilitates attachment of microtubules to the spindle pole body, nuclear division and microtubule assembly. Ubiquitination of γ-tubulin by breast cancer 1 protein (BRCA1) is a crucial step in the regulation of centrosome number. Overexpression of γ-tubulin is observed in lung cancer. Tubulin γ 2 (TUBG2) plays a vital role in cell growth. Aberration in the γ-tubulin gene alters microtubule assembly. The expression levels of γ-tubulin can be considered as an important prognostic indicator for patients with astrocytomas.

Physical form

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

Storage and Stability

Store at –20 °C. For continuous use, the product may be stored at 2-8 °C for up to one month. For extended storage, freeze in working aliquots at –20 °C. Repeated freezing and thawing, or storage in “frost-free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.
