Centrosomes recruit γ-tubulin containing complexes (γTuCs) that nucleate microtubules. Most γTuCs are present in the cytosol where their microtubule nucleation activity is inhibited. How γTuCs are activated at centrosomes is an unsolved question. Here I will investigate how phosphorylation converts a centrosomal protein SPD-5 in C. elegans into mitotically active γTuC docking sites. I will employ biochemical assays in combination with advanced imaging technology to link the structural remodeling of SPD-5 to the functional mechanisms in mitotic spindle assembly.
