WebApr 28, 2011 · Ferroportin expression was shown to be regulated translationally by intracellular iron through the iron-responsive element/iron-regulatory protein system and transcriptionally by heme, and these responses allow macrophages to match their iron export capacity to the fluctuating iron and heme load caused by episodic … WebAug 5, 2013 · Many mRNAs encoding proteins involved in iron metabolism contain iron regulatory elements (IREs) in their 5’ or 3’ UTRs. When cytosolic iron is low, iron regulatory proteins (IRPs) bind to the 5’ IRE thereby preventing translation (in the case of ferritin or Fpn1) or to the 3’ IRE thereby stabilizing mRNA (as seen for TfR1 or DMT1).

WebH-ferritin deletion is incompatible with life and its conditional deletion in the gut deregulates the fine mechanism of iron absorption causing iron overload.19 L-ferritin heterozygous mutations are rare and limited to the 5’ iron regulatory element (IRE) - leading to escape from iron regulatory protein (IRP) control and constitutive high ... WebOct 1, 1999 · Introduction. Iron is an essential nutrient and a potential toxin. The cloning of the iron-regulatory proteins (IRPs) and understanding of their interaction with iron … In 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 or IRBP). The IRE is found in UTRs (untranslated regions) of various mRNAs whose products are involved in iron metabolism. For … See more The two leading theories describe how iron probably interacts to impact posttranslational control of transcription. The classical theory suggests that IRPs, in the absence of iron, bind avidly to the mRNA IRE. When … See more Genes known to contain IREs include FTH1, FTL, TFRC, ALAS2, Sdhb, ACO2, Hao1, SLC11A2 (encoding DMT1), NDUFS1, SLC40A1 (encoding … See more • 5'UTR • IRP See more Many genes regulated by IREs have clear and direct roles in iron metabolism.
