RBP4 protein acts as a retinol-binding protein, essential for transporting retinol in blood plasma. It facilitates the delivery of retinol from the liver to peripheral tissues and likely transfers bound all-trans retinol to STRA6 for cell membrane transport. Interactions with TTR prevent kidney glomeruli filtration loss. Direct interaction with STRA6 underscores RBP4's role in intricate retinol transport and distribution processes in the body. RBP4 Protein, Human is the recombinant human-derived RBP4 protein, expressed by E. coli , with tag free.
