Plays a critical role in the phospholipid salvage pathway from lysosomes to the cytosol (PubMed:36161949).Mediates the rate-limiting，proton-dependent，lysosomal efflux of lysophospholipids，which can then be reacylated by acyltransferases in the endoplasmic reticulum to form phospholipids (PubMed:36161949).Selective for zwitterionic headgroups such as lysophosphatidylcholine (LPC) and lysophosphatidylethanolamine (LPE)，can also transport lysophosphatidylglycerol (LPG)，but not other anionic lysophospholipids，sphingosine，nor sphingomyelin (PubMed:36161949).Transports lysophospholipids with saturated，monounsaturated，and polyunsaturated fatty acids，such as 1-hexadecanoyl-sn-glycero-3-phosphocholine，1-(9Z-octadecenoyl)-sn-glycero-3-phosphocholine and 1-(4Z，7Z，10Z，13Z，16Z，19Z-docosahexaenoyl)-sn-glycero-3-phosphocholine，respectively (PubMed:36161949).Can also transport lysoplasmalogen (LPC with a fatty alcohol) such as 1-(1Z-hexadecenyl)-sn-glycero-3-phosphocholine (PubMed:36161949).
