... Drosophila , the Ets protein Pointed P1 (PntP1) is required to generate INPs from type II neuroblasts. Here, we investigated how PntP1 promotes INP generation. By generating pntP1 -specific mutants and using RNAi knockdown, we show that the loss of PntP1 leads to both an increase in type II neuroblast number...
