Summary

This protein belongs to the lipocalin family and is the specific carrier for retinol (vitamin A alcohol) in the blood. It delivers retinol from the liver stores to the peripheral tissues. In plasma, the RBP-retinol complex interacts with transthyretin which prevents its loss by filtration through the kidney glomeruli. A deficiency of vitamin A blocks secretion of the binding protein posttranslationally and results in defective delivery and supply to the epidermal cells. [provided by RefSeq, Jul 2008]

Forensic Context

A study in mice demonstrated that the RBP4 was characteristically down-regulated in the liver following in vivo exposure to α-particles, specifically from Kupffer cell and endothelial cell irradiation, as well as from neutron and γ-ray exposures, compared to non-irradiated controls [Roudkenar et al. DOI:10.1269/jrr.07078].
