WebIRE-BP resembles mitochondrial aconitase and has aconitase activity, enabling it to sense iron levels. When iron is scarce, the reduced form (3Fe-4S) of the protein binds the IRE … Webing of the IRE-BP to IREs is reversibly regulated by the iron status of the cell. The IRE-BP is highly conserved among human, rat, mouse, and rabbit, and it is identical to the cytosolic form of aconitase. In this study, we dem- onstrate that a distinct human gene encoding a protein which is 57% identical to the initially described IRE-BP,

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 example, the mRNA of ferritin (an iron storage protein) contains one IRE in its 5' UTR. Whe…

WebAs discussed above, the IRE is a conserved nucleotide motif present in the 5′ noncoding region of all ferritin mRNAs. During periods of low cellular iron, the IRP binds the IRE … WebThe IRE-BP is highly conserved among human, rat, mouse, and rabbit, and it is identical to the cytosolic form of aconitase. In this study, we demonstrate that a distinct human gene encoding a protein which is 57% identical to the initially described IRE-BP, now referred to as iron regulatory protein 1 or IRP1, is also capable of binding to IREs ...
