function
FUNCTION: Lipid transporter involved in lipid countertransport between the Golgi complex and membranes of the endoplasmic reticulum: specifically exchanges sterol (cholesterol) with phosphatidylinositol 4-phosphate (PI4P, 1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol 4-phosphate)), which is subsequently degraded by the SAC1/SACM1L phosphatase in the endoplasmic reticulum. Binds cholesterol and a range of oxysterols including 25-hydroxycholesterol. Cholesterol binding promotes the formation of a complex with PP2A and a tyrosine phosphatase which dephosphorylates ERK1/2, whereas 25-hydroxycholesterol causes its disassembly. Regulates cholesterol efflux by decreasing the stability of the relatively short lived ABCA1 protein (an important point of control for cholesterol efflux activity). {ECO:0000250|UniProtKB:P22059}.
