Functionally overlapping intra- and extralysosomal pathways promote bis(monoacylglycero)phosphate synthesis in mammalian cells
Abstract Bis(monoacylglycero)phosphate (BMP) is a major phospholipid constituent of intralumenal membranes in late endosomes/lysosomes, where it regulates the degradation and sorting of lipid cargo.Recent observations suggest that the Batten disease-associated protein CLN5 functions as lysosomal BMP synthase.Here, we show that transacylation reacti
