Prospero prevents lineage-specific loss and gain by regulating cyclin E and mitosis during Drosophila neurogenesis.
In Drosophila, neuroblasts (NBs) undergo self-renewing asymmetric divisions to generate ganglion mother cells (GMCs). Each GMC undergoes a terminal asymmetric division to generate two neurons. It was previously suggested that the loss of function of the chromatin-binding protein Prospero causes dedifferentiation of NB...
