Binds retinol. Also binds the fluorescent fatty acid 11-((5-dimethylaminonaphthalene-1-sulfonyl)amino)undecanoic acid (DAUDA). The long chain fatty acid oleic acid can act competitively to displace bound DAUDA and retinol. Not glycosylated. Belongs to the fatty-acid and retinol-binding protein (FARBP) family.
