CendR peptides, based on a C-terminal motif found in neuropilins, have been used to promote drug delivery to tumours by endocytosis. Pang et al. show that CendR peptides are taken up by a mechanistically distinct form of endocytosis that resembles macropinocytosis, and is stimulated by nutrient depletion.
