Some enhancers can limit their activities to specific spatial–temporal domains by enhancer suboptimization. Ou et al. find that classical dendritic cell (cDC) development depends on Irf8 suboptimization, which prevents unwanted IRF8 autoactivation in developing cDC2s while maximizing IRF8 expression in developed cDC1s.
