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.

WebThis protein is referred to by different groups as “iron regulatory factor (IRF)”, “IRE-binding protein (IRE-BP)”, “ferritin repressor protein (FRP)” or “p90”. Keywords. Translational … 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.
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. High cellular iron changes the IRE/P-90 interaction to relax the translational block and allow polyribosome formation. 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 …
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. Web(15) Binding of the IRE-BP represses ferritin translation and represses degradation of the TfR mRNA. (16) Yet in doing so it presents an angled mirror-polished cliff face of glass, which has been reflecting the sun straight across into the Lloyds offices across the road – the seminal "inside-out" machine that Rogers designed 30 years earlier ...

Web(16) A stimulatory estrogen response element (ERE) was localized to a 32-bp region between -547 and -516 bp. (17) In these genes, two ERE homologues, which have only low, if any, regulatory capacity on their own, act synergistically to achieve high estrogen inducibility. ironmix storeWebAbstract. Iron regulatory elements (IREs) are a family of 28 nucleotide, non-coding elements which regulate the translation of ferritin mRNA (iron storage), erythroid delta … ironmind30In 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.
