WebNov 16, 2005 · IREs are regulatory elements that encode a phylogenetically defined sequence-structure motif that provide a specific recognization site for the IRE-binding proteins (IRE-BP1 or IRE-BP2). Iron starvation of cells induces high affinity binding of cytoplasmic IRE-BP to an IRE, which has at least two distinct known biological … WebDec 15, 1992 · IRE-BP is required in the posttranscriptional regulation of ferritin mRNA translation and stabilization of transferrin receptor mRNA. In spite of substantial homology between the amino acid sequences of mammalian mitochondrial aconitase and IRE-BP, the mitochondrial protein does not bind IREs.

WebTo read, Please Download here. The iron-responsive element binding protein (IRE-BP) is a cytosolic protein that binds a highly conserved sequence in the untranslated regions of mRNAs involved in iron metabolism including ferritin, transferrin receptor, and erythroid 5-aminolevulinate acid synthase. Iron-responsive element-binding protein (IRE-BP) binds to these mRNA sequences. On its own, the IRE-BP binds to the IREs of ferritin and transferrin receptor mRNA. But, when iron binds to the IRE-BP, the IRE-BP changes shape with the result that the IRE-BPs can no longer bind the ferritin mRNA.
