During interphase centrosomes are held together by an extended proteinaceous linker that connects the proximal ends of the mother and daughter centriole. This linker is disassembled at the onset of mitosis in a process known as centrosome disjunction, thereby facilitating centrosome separation and bipolar spindle formation. The NIMA-related kinase Nek2A is implicated in disconnecting the centrosomes through disjoining the linker proteins C-Nap1 and rootletin. However, the mechanisms controlling centrosome disjunction remain poorly understood. Here, we report that two Hippo pathway components, the mammalian sterile 20-like kinase 2 (Mst2) and the scaffold protein Salvador (hSav1), directly interact with Nek2A regulating its ability to localize to centrosomes and phosphorylate C-Nap1 and rootletin. Furthermore, we show that the hSav1-Mst2-Nek2A centrosome disjunction pathway becomes essential for bipolar spindle formation upon partial inhibition of the kinesin-5 Eg5. We propose that hSav1-Mst2-Nek2A and Eg5 have distinct but complementary functions in centrosome disjunction.
