How such signalling coordinates different organelle functions within adaptive responses remains unknown. Membrane traffic is a fundamental process in which membrane fluxes need to be sensed for the adjustment of cellular requirements and homeostasis. Studying endoplasmic reticulum-to-Golgi trafficking, we found that Golgi-based, KDEL receptor-dependent signalling promotes lysosome repositioning to the perinuclear area, involving a complex process intertwined to autophagy, lipid-droplet turnover and Golgi-mediated secretion that engages the microtubule motor protein dynein-LRB1 and the autophagy cargo receptor p62/SQSTM1. This process, here named ‘traffic-induced degradation response for secretion’ (TIDeRS) discloses a cellular mechanism by which nutrient and membrane sensing machineries cooperate to sustain Golgi-dependent protein secretion. © 2019, The Author(s).enAutophagyCell Line, TumorCell NucleusDyneinsEndoplasmic ReticulumGolgi ApparatusHeLa CellsHumansLipid DropletsLysosomesMicroscopy, Electron, TransmissionMicrotubulesProtein TransportReceptors, PeptideSequestosome-1 ProteinSignal TransductionArtículoAtribución 4.0 Internacional (CC BY 4.0)10.1038/s41467-019-08501-w
