Iron regulatory proteins (IRP-1 and IRP-2) are cytoplasmic mRNA-binding proteins that control intracellular iron levels by regulating the translation of ferritin, Tfrs, and other proteins congaing iron-responsive element (IRE) located at the 5′-UTR. IRP binds to IREs with high affinity in situation of iron starvation. Binding of IRP to IRE of ferritin represses its transcription. However, when cells are iron replete, IRPs lose their capacity to bind IREs, allowing efficient translation of ferritin and reducing Tfr mRNA half-life. Although IRP1 and IRP-2 share significant protein sequence homology, they differ in tissue distribution and mode of regulation. IRP-2/IRE-BP2 (rat/human 963 aa) is relatively less abundant than IRP-1 and lacks aconitase activity. It has a unique 73-aa insertion in the N-terminus. In the presence of high iron levels, IRP-2 is rapidly targeted to proteasome-mediated degradation. Although, both IRPs bind the consensus IREs, it is also shown that IRP-2 can recognize an exclusive IRE subset.
