Recombinant Human Oxysterol-binding protein-related protein 2 (OSBPL2)

Uniprot Id

Q9H1P3

Target Species

Human

Target Name

OSBPL2

Target Full Name

Oxysterol-binding protein-related protein 2

Target Function

Intracellular transport protein that binds sterols and phospholipids and mediates lipid transport between intracellular compartments. Increases plasma membrane cholesterol levels and decreases phosphatidylinositol-4,5-bisphosphate levels in the cell membrane. Binds phosphoinositides, such as phosphatidylinositol-4,5-bisphosphate. Exhibits strong binding to phosphatidic acid and weak binding to phosphatidylinositol 3-phosphate. Binds cholesterol, dehydroergosterol, 22(R)-hydroxycholesterol and 25-hydroxycholesterol (in vitro).

Target Involvement

Deafness, autosomal dominant, 67 (DFNA67)

Target Subcellular Location

Cytoplasm, cytosol. Lipid droplet. Cell membrane; Peripheral membrane protein; Cytoplasmic side.

Target Protein Families

OSBP family

Target Tissue Specificity

Widely expressed.

Target Background

This gene encodes a member of the oxysterol-binding protein (OSBP) family, a group of intracellular lipid receptors. Most members contain an N-terminal pleckstrin homology domain and a highly conserved C-terminal OSBP-like sterol-binding domain, although the encoded protein contains only the sterol-binding domain. 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.
