Lecithin:Retinol Acyltransferase Is Critical for Cellular Uptake of Vitamin A from Serum Retinol-binding Protein

Background: Cellular uptake of retinol bound to its serum binding protein depends on a cell surface receptor. Results: Functional coupling of this receptor with lecithin:retinol acyltransferase is required for the regulated cellular uptake of retinol. Conclusion: The lecithin: retinol acyltransfe…
