TUB4, the gene for Saccharomyces cerevisiae γ-Tubulin, encodes a 473 amino acid structural protein that localizes to the spindle pole body. γ Tubulin, an essential protein for cell growth, organizes microtubule arrays in the nucleus and cytoplasm. γ Tubulin-depleted cells fail to form functional spindles and arrest during nuclear division. γ Tubulin associates with spindle body components Spc97 and Spc98 to form the γ Tubulin complex. The budding yeast γ Tubulin complex contains one molecule each of Spc97 and Spc98 and two molecules of γ Tubulin. In the SPB, Spc110 binds Spc97 and Spc98 of the γ Tubulin complex. 2D gel analysis indicates five isoforms of γ Tubulin. The phosphorylation of γ Tubulin at Tyr 445 plays a regulatory role in microtubule formation. The incidence rate for this phosphorylation event peaks during G1.
Homo Sapiens (Human)
