IRP1 IRP2

IRP1 IRP2 The two proteins that act as sensors of iron changes in the cytoplasm, in duodenal epithelial cells, are the iron regulatory proteins, IRP1 (Iron Regulatory Protein 1) and IRP2 (Iron Regulatory Protein 2). The regulation of key enzymes involved in iron hemostasis, occurs at the translational level, through Iron Responsiv Element, i.e....
