Target

Full Name
Oxysterol Binding Protein Like 2
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 (PubMed:30581148).
Binds phosphoinositides, such as phosphatidylinositol-4,5-bisphosphate (PubMed:30581148).
Exhibits strong binding to phosphatidic acid and weak binding to phosphatidylinositol 3-phosphate (PubMed:11279184).
Binds cholesterol, dehydroergosterol, 22(R)-hydroxycholesterol and 25-hydroxycholesterol (in vitro) (PubMed:17428193, PubMed:19224871, PubMed:30581148).

Involvement in disease
Deafness, autosomal dominant, 67 (DFNA67):
A form of non-syndromic sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information.
