LP15378-0   Retinol binding protein
Retinol binding proteins (RBPs) are a family of carrier proteins that bind retinol. The term "retinol binding protein" (singular) in the clinical literature commonly refers to the circulating form that transports retinol from the liver to peripheral tissues. This form, RBP4, is a low molecular weight protein 21kD in size that is sometimes referred to as alpha-2-microglobulin in older literature (for example see https://www.tandfonline.com/doi/abs/10.3109/00365597409132815). Because RBP4 is extensively reabsorbed by the kidney tubules, very little normally appears in excreted urine. An increase in the urinary excretion of retinol binding protein indicates impaired proximal tubular function. This can be caused by renal tubulointerstitial nephritis, tubular toxicity from heavy metal or nephrotoxic drug exposure, glomerulonephropathies and renal vasculopathies PMID: 11961401.
