Description	Our results suggest that ORP5 may cooperate with NPC1 to deliver cholesterol from LE/LY to the ER.
Description of experimental evidence	The protein was validated by filipin staining, fluorescence microscopy, immunofluorescence, confocal microscopy, coimmunoprecipitation, GST pull-down assay and immunoblot analysis in CHO-K1 cells, HeLa cells, HEK293 cells and Npc1-null2-2 cells.

Description	Cholesterol delivery to the ER required the sterol-, phosphatidylinositol 4-phosphate-, and vesicle-associated membrane protein-associated protein (VAP)-binding activities of ORP1L, as well as NPC1 expression.
Description of experimental evidence	The protein was validated by PCR analysis, immunoblotting, immunoprecipitation, fluorescence and electron microscopy in HeLa cells and HEK293 cells, which regulates Cholesterol Egress from the Endo-Lysosomal System.
