RBP-4 Human Recombinant produced in E.Coli is single, a non-glycosylated, Polypeptide chain containing 183 amino acids fragment (19-201) corresponding to the mature Retinol Binding Protein, having a total molecular mass of 25.57kDa and fused with a 4.5kDa amino-terminal hexahistidine tag. The RBP4 is purified by proprietary chromatographic techniques.
Retinol binding protein 4(RBP4) belongs to the lipocalin family and is the specific carrier for retinol (vitamin A alcohol) in the blood. This protein was found to be expressed and secreted by adipose tissue, and was strongly associated with insulin resistance. 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.RBP4 delivers retinol from the liver to the peripheral tissues.
