RBP4 - retinol binding protein 4 Gene
Also Known as RDCCAS; MCOPCB10
Species: Homo sapiens
About RBP4
This gene has 3 transcripts (splice variants), 202 orthologues and is associated with 6 phenotypes. Biased expression in liver (RPKM 2545.8) and fat (RPKM 387.7).
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]
