Dishevelled is a NEK2 kinase substrate controlling dynamics of centrosomal linker proteins

• Wnt signaling is an important orchestrator of embryonic development. We provide evidence that Wnt scaffolding protein Dishevelled (DVL) contributes to the dissolution of centrosomal linker, preceding separation of centrosomes. We show that DVL accumulates toward mitosis, and its centrosomal function is controlled by NEK2. Our data demonstrate that DVL is required for the removal of linker proteins from centrosome, an event necessary for the correct formation of a bipolar spindle and cell cycle transition. This surprising function of DVL creates a mechanistic basis for the novel crosstalk between Wnt signaling pathways and the centrosome cycle.
