In this project  we address how polarity cues control the organization of the mitotic cell cortex to regulate the spatial and temporal dynamics of the molecular spindle orientation machinery  essential to position spindles. We will use the mammalian polarity aPKCs as a paradigm for phosphorylation-dependent events that drive mitosis, spindle orientation and cell fate, as we showed previously that this kinase controls mammalian spindle orientation and cell fate in vivo under homeostatic and pathogenic conditions.
