8.A.180. The Retinol-binding protein (RBP) Family 

RBP4 mediates retinol transport in blood plasma (Peterson 1971). It delivers retinol from the liver stores to the peripheral tissues and transfers the bound all-trans retinol to STRA6, that then facilitates retinol transport across the cell membrane (Berry et al. 2012). It is a small molecule transporter (Xiong et al. 2021).
