Protein attributes

Sequence length	807 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	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. Ref.4 Ref.6
Subunit structure	Homodimer or homotrimer. Interacts with VAPA. Ref.15
Subcellular location	Cytoplasm. Golgi apparatus membrane; Peripheral membrane protein. Note: When bound to oxysterols, translocates to the periphery of Golgi membranes.
Tissue specificity	Widely expressed. Ref.2
Domain	The PH and Ala/Gly-rich domains control cholesterol binding without affecting 25-hydroxycholesterol binding By similarity. The second coiled-coil domain is required for interaction with the tyrosine phosphatase By similarity.
Sequence similarities	Belongs to the OSBP family. Contains 1 PH domain.
Sequence caution	The sequence AAH63121.1 differs from that shown. Reason: Aberrant splicing.
