Cilia assembly is inhibited by activation of the PI3K/Akt pathway by the serum factor lysophosphatidic acid, independent of cell cycle alterations. Walia et al. show that activated Akt phosphorylates WDR44, stabilizing its effector-based binding to Rab11 and preventing Rabin8 preciliary trafficking and ciliogenesis initiation.
