Human Retinol Binding Protein 4 (RBP4)
Retinol binding protein 4(RBP4), originally known as a specific transport of retinol in blood, is also an inflammatory and insulin resistance marker. Serum levels of RBP4 increased in insulin resistant and diabetes. Studies both in human and animal suggested that serum levels of RBP4 plays a key role in the link between obesity, insulin resistant and diabetes.
RBP4 is normally excreted into the urine but accumulate in the serum during renal failure. Elevated serum retinol-binding protein 4 concentrations are associated with chronic kidney disease.
Expressed in E.Coli. Mw: 24.4 kDa (calculated).
