Description_x000D_ General description_x000D_ 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._x000D_ Specificity_x000D_ The antibody recognizes an epitope located within the N-terminal region of γ-tubulin._x000D_ Immunogen_x000D_ synthetic γ-tubulin peptide, conjugated to KLH_x000D_ Application_x000D_ Monoclonal Anti-γ-Tubulin antibody produced in mouse has been used in following studies:_x000D_ • Western blot analysis_x000D_ • Immunohistochemistry_x000D_ • Immunocytology_x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide._x000D_ Storage and Stability_x000D_ 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._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Biochem/physiol Actions_x000D_ 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.
