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.
