Making sure late endosomes are on time

Early endosomes collect and sort cargoes before maturing into late endosomes that ferry those cargoes to the lysosome. Liu et al. identify two proteins that spur early endosomes to transform and thus help ensure that cellular deliveries occur on schedule (1). As an early endosome morphs into a late endosome, it revamps its molecular composition. Early endosomes carry the GTPase Rab5, which attr...
