Phosphorylation Remodels the Mitotic Centrosome Matrix to Generate Bipartite γ-Tubulin Complex Docking Sites

Scientists showed that SPindle Defective-5) contains two regions, phospho-regulated γTuC binding region 1 (PRGB1) and PRGB2, that are each sufficient for polo-like kinase 1 phosphorylation–regulated γTuC binding.
