Iron sensing in mammals and plants. In mammalian cells, Fe is sensed via IRP1 and IRP2, which bind to IREs to regulate the translation of genes involved in the uptake and storage of Fe. In the presence of cytosolic Fe, IRP1 loses its sensing function and acts as an aconitase; both IRP1 and IRP2 are targeted for proteasomal degradation …Web
