Gamma-tubulin is a ubiquitous phylogenetically conserved member of tubulin superfamily. Gamma is a low abundance protein present within the cells in both various types of microtubule-organizing centers and cytoplasmic protein complexes. Gamma-tubulin recruits the alpha/beta-tubulin dimers that form the minus ends of microtubules and is thought to be involved in microtubule nucleation and capping.
