WebIron homeostasis in mammals is mainly regulated by a set of interlocking regulatory systems, including: (i) Hepcidin–ferroportin (FPN1) mediated regulation of serum iron levels, (ii) iron regulatory proteins (IRPs)/iron responsive element (IRE) mediated regulation of intracellular iron homeostasis, (iii) hypoxia inducible factor-2α (HIF2α) … WebOct 2, 2008 · The interactions of iron responsive elements (IREs) with iron regulatory proteins (IRPs) coordinately regulate the expression of the genes involved in iron uptake, use, storage, and export at the post-transcriptional level, and represent the main regulatory network controlling cell iron homeostasis.

WebFeb 24, 2024 · The regulatory outcome depends on the IRE position in the mRNA. In iron-restricted (IR) conditions, if the IRE is in the 5′-UTR, this IRP protein interaction causes a translational blockage. However, if the IRE is in the 3′-UTR, this interaction promotes mRNA stability by suppressing mRNA degradation, and the protein is synthesized [ 2 ]. WebA central role in regulating iron/oxygen chemistry in animals is played by mRNA translation or turnover via the iron responsive element (IRE)/iron regulatory protein (IRP) system. The IRE family is composed of three-dimensional RNA structures located in 3′ or 5′ untranslated regions of mRNA.
