part of endosome membrane membrane protein complex ER-to-endosome phospholipid transfer complex https://github.com/geneontology/go-ontology/issues/15338 pg 2021-03-10T11:27:24Z Lipid transfer complex that is responsible for the non-vesicular transport of phospholipids, such as phosphatidylserine, from the endoplasmic reticulum to the endosome. It resides in the endosomal (acceptor) membrane and binds to specific lipids on the donor membrane at the ER-endosome contact site. GO:0140622 cellular_component
