Description

Description générale

γ-Tubulin (48 kDa) is a widely expressed and highly conserved protein within the microtubule organizing centers (MTOCs) or centrosome in eukaryotic cells.

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.

Spécificité

The sequence is highly specific for Drosophila γ-tubulin and is not found in γ-tubulin of other species or other members of the tubulin family such as α-, β-, δ-, and ε-tubulins.

Immunogène

synthetic peptide corresponding to the C-terminus of Drosophila γ-tubulin (amino acids 441-457 with N-terminal added cysteine-glycine), conjugated to KLH.

Application

Anti-γ-Tubulin (QG-17) antibody has been used in immunoblotting and immunostaining.

Actions biochimiques/physiologiques

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.
