[5][6][7] This gene encodes a member of the oxysterol-binding protein (OSBP) family, a group of intracellular lipid receptors.

In vitro studies have shown that the encoded protein can bind strongly to phosphatic acid and weakly to phosphatidylinositol 3-phosphate, but cannot bind to 25-hydroxycholesterol.

The protein associates with the Golgi apparatus.

Transcript variants encoding different isoforms have been described.
