Protein Structure
|
|
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. {ECO:0000269PubMed:15746430, ECO:0000269PubMed:18450749}.
|
Subcellular Localization |
Cytoplasm. Golgi apparatus membrane; Peripheral membrane protein. Note=When bound to oxysterols, translocates to the periphery of Golgi membranes.
|
Disease Associations |
|
Tissue Specificity |
Widely expressed. {ECO:0000269PubMed:11278871}.
