WebAug 5, 2013 · Many mRNAs encoding proteins involved in iron metabolism contain iron regulatory elements (IREs) in their 5’ or 3’ UTRs. When cytosolic iron is low, iron regulatory proteins (IRPs) bind to the 5’ IRE thereby preventing translation (in the case of ferritin or Fpn1) or to the 3’ IRE thereby stabilizing mRNA (as seen for TfR1 or DMT1). WebIRP (Iron Regulatory Proteins): IRP1 and IRP2 are cytosolic proteins that sense iron concentration and posttranscriptionally regulate the expression/translation of iron-related genes to maintain cellular iron homeostasis. IRP1 is an RNA binding protein in its apo form when iron is low.
