WebUnder conditions of iron deficiency, iron-regulatory proteins IRP1 and IRP2 bind to the iron-responsive elements (IREs) located in either the 5′ or 3′ untranslated regions (UTRs) of the indicated mRNAs, thus repressing mRNA translation (a) or preventing mRNA degradation (b), respectively. 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). sims 2 bon voyage food
