WebMar 1, 2024 · Regulation of TfR1 and Ft expression by the IRE/IRP system. Ferritin (both FTL and FTH) mRNA has one IRE in 5′-untranslated region (UT) and TfR1 mRNA has five IREs in the middle of the 3′-UT. IRPs binds to the IREs in iron-depleted condition. Binding of IRP to Ft IRE suppresses the translation of Ft, whereas, IRP-binding to TfR1 mRNA ...
