Spatiotemporal coordination of the RSF1-PLK1-Aurora B cascade establishes mitotic signaling platforms

During cell division, chromosome alignment is engendered by connection of microtubules to kinetochores, coordinated by Aurora B and PLK1. Here, the authors show that the RSF1-PLK1 axis creates an activating phosphorylation on T236 in the GT motif of Aurora B and this is indispensable for Aurora B activation
