Immunizing Peptide (Blocking)
Our Abpromise guarantee covers the use of ab5915 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
WB: Use at a concentration of 1 - 3 µg/ml. Predicted molecular weight: 89.4 kDa.
Not yet tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
FunctionBinds 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.
Tissue specificityWidely expressed.
Sequence similaritiesBelongs to the OSBP family.
Contains 1 PH domain.
DomainThe 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.
Cellular localizationCytoplasm. Golgi apparatus membrane. When bound to oxysterols, translocates to the periphery of Golgi membranes.
