Cell polarity is regulated by independent pathways that are controlled by Wnt- or Cdc42-mediated signalling. Now, glycogen synthase kinase 3 (GSK-3), an established component of the Wnt pathway, is shown to interact with Par6–protein kinase C ζ (PKCζ), a complex that transduces Cdc42 signals. This exciting result suggests a potential point of conversion between these previously distinct pathways.
