Summary
OSBP (oxysterol binding protein, HGNC:8503) is a protein-coding gene on chromosome 11q12.1, encoding Oxysterol-binding protein 1 (P22059). 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)), del…. It is a selective cancer dependency (DepMap: 43.0% of cell lines).
Oxysterol binding protein is an intracellular protein that is believed to transport sterols from lysosomes to the nucleus where the sterol down-regulates the genes for the LDL receptor, HMG-CoA reductase, and HMG synthetase

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)), delivering sterol to the Golgi in exchange for PI4P, 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).
Subunit / interactions. Homodimer or homotrimer. Interacts (via FFAT motif) with VAPA. Interacts (via C-terminus) with RELCH (via the third HEAT repeat). Found in a complex composed of RELCH, OSBP1 and RAB11A.
Subcellular location. Cytoplasm. Cytosol. Perinuclear region. Golgi apparatus membrane. Endoplasmic reticulum membrane. Golgi apparatus. trans-Golgi network.
Tissue specificity. Widely expressed.
Domain organisation. The FFAT motif is required for interaction with VATA and proper localization of the protein. The PH and the Ala/Gly-rich domains control cholesterol binding without affecting 25-hydroxycholesterol binding. The second coiled-coil domain is required for interaction with the tyrosine phosphatase.
Similarity. Belongs to the OSBP family.
