For the efficient trafficking of lysosomal proteins, the cationic-dependent and -independent mannose 6-phosphate receptors and sortilin must bind cargo in the Golgi apparatus, be packaged into clathrin-coated trafficking vesicles and traffic to the endosomes. Once in the endosomes, the receptors release their cargo into the endosomal lumen and recycle back to the Golgi for another round of trafficking, a process that requires retromer. In this study, we demonstrate that palmitoylation is required for the efficient retrograde trafficking of sortilin, and the cationic-independent mannose 6-phosphate as palmitoylation-deficient receptors remain trapped in the endosomes. Importantly, we also show that palmitoylation is required for receptor interaction with retromer as nonpalmitoylated receptor did not interact with retromer. In addition, we have identified DHHC-15 as the palmitoyltransferase responsible for this modification. In summary, we have shown the functional significance of palmitoylation in lysosomal receptor sorting and trafficking.
