WebMay 15, 1992 · The iron-responsive element-binding protein (IRE-BP) is an RNA-binding protein that regulates the expression of several mRNAs in response to availability of cellular iron. The iron-dependent control of IRE-BP activity has been reconstituted in vitro. 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,

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. WebA 90-kilodalton protein, called the IRE binding protein (IRE-BP), binds to the IRE and acts as a translational repressor. IREs also explain the iron-dependent control of the degradation of the mRNA encoding the transferrin receptor.

WebJan 18, 1994 · The iron-responsive element-binding protein (IRE-BP) binds to specific stem-loop RNA structures known as iron-responsive elements (IREs) present in a variety of cellular mRNAs (e.g., those encoding ferritin, erythroid 5-aminolevulinate synthase, and transferrin receptor). Expression of these genes is regulated by interaction with the IRE-BP. WebMar 17, 1992 · The iron regulatory element (IRE) in the 5'-untranslated region of ferritin mRNA interacts with a specific regulator protein (P-90, IRE-BP, or FRP) to block translation.

WebA cytosolic protein binds in vitro to the IREs of both mRNAs. The IRE-binding protein (IRE-BP) is shown to require free sulfhydryl groups for its specific interaction with the IRE. Treatment of lysates with reducing agents increases the binding activity, whereas agents that block sulfhydryls inhibit binding.

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… WebThe synthesis of ferritin subunits is regulated at the translational level by iron through interaction with the cytoplasmic IRP or IRE-binding protein. As discussed above, the IRE is a conserved nucleotide motif present in the 5′ noncoding region of all ferritin mRNAs.
