Repression of Manduca sexta ferritin synthesis by IRP1/IRE interaction.

Mammalian ferritin subunit synthesis is controlled at the translational level by the iron regulatory protein 1 (IRP1)/iron responsive element (IRE) interaction. Insect haemolymph ferritin subunit messages have an IRE in the 5'-untranslated region (UTR). We have shown that recombinant M.
