CC -!- FUNCTION: RBP delivers retinol from the liver stores to the peripheral
CC tissues. In plasma, the RBP-retinol complex interacts with
CC transthyretin, this prevents its loss by filtration through the kidney
CC glomeruli. {ECO:0000250|UniProtKB:P04916}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:1740159}.
CC -!- SIMILARITY: Belongs to the calycin superfamily. Lipocalin family.
CC {ECO:0000305}.
