Rabbit Anti-Human TUBG1 polyclonal antibody for IHC-P. Tubulin gamma, an essential structural protein for cell growth, organizes microtubule arrays in the nucleus and cytoplasm. Tubulin gamma-depleted cells fail to form functional spindles and arrest during nuclear division. Tubulin gamma associates with spindle body components Spc97 and Spc98 to form the Tubulin gamma complex. The phosphorylation of Tubulin gamma at Tyr445 plays a regulatory role in microtubule formation. The incidence rate for this phosphorylation event peaks during G1.
