Oxysterol binding protein 1
Oxysterol-binding protein 1
Binds cholesterol and a range of oxysterols. Cholesterol binding promotes the formation of a complex with PP2A and a tyrosine phosphatase which dephosphorylate ERK1/2, whereas 25-hydroxycholesterol causes its disassembly. Regulates cholesterol efflux by decreasing ABCA1 stability.
Belongs to the OSBP family. Contains 1 PH domain.
The PH and 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.
Cytoplasm. Golgi apparatus membrane. When bound to oxysterols, translocates to the periphery of Golgi membranes.
