Human Retinol binding protein (RBP) is responsible for binding and transporting retinol (vitamin A). Human RBP has a binding site for one molecule of retinol and circulates in the plasma together with prealbumin in the form of a protein complex in a molar ratio of 1:1. This binding to prealbumin prevents greater glomerular losses of the human retinol-binding protein. Only the retinol-free form of the retinol-binding protein, which has no affinity for prealbumin, undergoes glomerular filtration unhindered as a result of its low molecular weight; Human RBP is re-absorbed by the tubular cells and catabolized there.
