title: Cellular retinol-binding protein functions in the regulation of retinoid metabolism.
abstract: A microsomal retinyl ester hydrolase from rat tissues is activated by apo-cellular retinol-binding protein, which thus regulates the availability of retinol either for binding to serum retinol-binding protein or for metabolic oxidation. Microsomal retinal synthesis was found to occur in rat tissues with holo-cellular retinol-binding protein as substrate. Retinal could be further oxidized to retinoic acid by a cytosolic fraction.
