VPS13A and VPS13C are localized at contacts between the ER and either mitochondria or endo/lysosomes respectively. Top: schematic representation showing that both proteins can also localize at contacts between the ER and lipid droplets. Bottom fluorescence image (green: ER; blue: mitochondria or endo/lysosomes respectively; magenta: VPS13)
