Centrosome duplication requires a cartwheel-shaped protein complex containing the protein HsSAS-6, which acts as a template for centriole assembly. Ohta et al.show that HsSAS-6 is recruited to this structure by STIL and Plk4, and reveal that Plk4 phosphorylates STIL, stabilizing its interaction with HsSAS-6.
