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. Webdel ferro, e quindi il sistema IRP/IRE permette un controllo coordinato tra loro delle principali proteine coinvolte nel mantenimento dell’omeostasi del fer-ro. Tali proteine …

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 … WebIn 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 … ir light emitter

WebAug 1, 2006 · IRP binding to the IRE on the 5′-UTR of ferritin mRNA prevents translation of the protein. In this report we demonstrate that treatment of RAW 264.7 cells with iron (50 μg·mL −1 FAC, 18 h) and the resulting decrease in IRP activity will cause ∼ 10% of the total ferritin message to become polysome associated ( Fig. 6 ).

WebThe IRE/IRP regulatory system was first described in the late 1980s with the discovery of iron responsive elements (IREs) in the untranslated regions (UTRs) of the mRNAs encoding ferritin (both H- and L-subunits) and TfR1 ( Hentze et al., 1987; Casey et al., 1988; Müllner and Kühn, 1988 ); see Figure 3. orchid supplies south florida
