In molecular biology, the iron response element or iron-responsive element (IRE) is a short conserved stem-loop which is bound by iron response proteins (IRPs, also named IRE-BP or IRBP). The IRE is found in UTRs (untranslated regions) of various mRNAs whose products are involved in iron metabolism. For example, the mRNA of ferritin (an iron storage protein) contains one IRE in its 5' UTR. Whe… WebThe synthesis of ferritin subunits is regulated at the translational level by iron through interaction with the cytoplasmic IRP or IRE-binding protein. As discussed above, the IRE is a conserved nucleotide motif present in the 5′ noncoding region of all ferritin mRNAs.
