CEBPZ and ciliopathy: Overall, the mechanistic insight of our study and the discovery that Wnt signaling stimulates ciliary beating and improves CBF deficiency in ciliopathy models, may aid in the understanding of ciliopathies and inspire novel therapeutic interventions. Note added in proof: While this paper was in production, we reported that primary cilia are also WNT ┫PP1 signaling organelles61, indicating that the three main ciliary classes—flagella5, motile cilia (this work), and primary cilia—employ ciliary Wnt signaling for ciliogenesis.
