retinol binding protein

Also found in: Acronyms, Wikipedia.

retinol binding protein (RBP)

A single-chain polypeptide glycoprotein secreted in fat cells and the liver. It is a member of the alpha globulin family of plasma proteins. It binds and solubilizes retinol and protects it from oxidation. RBP 4 is elevated before the development of frank diabetes and appears to indicate insulin resistance.
