WebMay 11, 2010 · IREs are cis-acting regulatory motifs present in mRNAs that encode proteins involved in iron metabolism. They function as binding sites for two related trans-acting factors, namely the IRP-1 and -2. Among cis-acting RNA regulatory elements, the IRE is one of the best characterized. It is defined by a combination of RNA sequence and structure. WebAug 20, 2024 · Since the classic IREs have been identified in ferritin mRNA ( Aziz and Munro, 1987; Hentze et al., 1987 ), quite a few IRE-like structures have been proposed later in other mRNAs, of which the encoded proteins are not necessarily solely involved in iron homeostasis, e.g. 5′-aminolevulinate synthase 2 (ALAS2, a.k.a. eALAS), endothelial PAS … WebOct 1, 2008 · Iron (Fe) is an essential element in most physiological processes of the human organism.
