Advanced Science, EarlyView.This work maps 3′‐UTR APA across mouse fetal development and tissues, identifying conserved sequence determinants that influence pAS choice. In fetal brain tissues, complex APA dynamics during development are potentially regulated by RBPs like Rbm38, which restrict distal pAS usage.
