Retinol Binding Protein (RBP), a single-chain polypeptide glycoprotein, belongs to the a-globulin family of human plasma proteins and is the primary plasma transport protein for retinol (vitamin A1). RBP binds retinol in a 1:1 stoichiometry, serving not only to solubilize retinol but also to protect it from oxidation. Once in circulation, the RBP-retinol complex binds to one molecule of transthyretin (prealbumin), a plasma thyroxine-binding protein. This complex then delivers retinol to specific receptors of the retina, skin, gonads, lungs, salivary glands, and other tissues.
