type I cellular retinol-binding protein | i.e. RBP1, RBP1, but not RBP2, is required for the transport of water-insoluble substrates of retinoid pathway enzymes, e.g. of BCMO1, into the cell, and acts as an intracellular sensor of retinoid status that, when present as apo-RBP1, stimulates BCMO1 activity and the conversion of carotenoids to retinoids | Mus musculus | |
