Regulation of NB decommissioning by Imp/Syp RNA-binding proteins. Reduction of Imp prior to the ecdysone signaling during metamorphosis (indicated by the unfilled arrow) is permissive for the ecdysone receptor (EcR)- and mediator complex-mediated metabolic switch that triggers non-MB NB decommissioning. Syp then promotes Pros accumulation to terminate NB cycling by terminal differentiation.
