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. WebIron-responsive elements (IREs) are regulatory RNA elements which serve as specific binding sites for the IRE-binding protein (IRE-BP). Interaction between IREs and IRE-BP …
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 … 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.
WebDec 30, 2024 · The key interaction is between the iron response elements (IRE), which are sequences of mRNA that form short stem-loop structures, and IRE-BP, the protein that … WebNov 15, 1991 · A clone for the iron-responsive element (IRE)-binding protein (IRE-BP) has been transfected and expressed in mouse fibroblasts. The IRE-BP gene product binds IREs with high affinity and specificity. Amino acid alignments reveal that the IRE-BP is 30% identical to mitochondrial aconitase.

We describe the identification of extensive amino acid sequence homology between IRE-BP and two known isomerases, aconitase and isopropylmalate (IPM) isomerase. dfe try it out mtcIron-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. See more The iron-responsive element-binding proteins, also known as IRE-BP, IRBP, IRP and IFR , bind to iron-responsive elements (IREs) in the regulation of human iron metabolism. See more ACO1, or IRP1, is a bifunctional protein that functions as an iron-responsive element (IRE)-binding protein involved in the control of iron metabolism by binding mRNA to repress translation or degradation. It functions also as the cytoplasmic isoform … See more • IRE • Aconitase See more All cells use some iron, and must get it from the circulating blood. Since iron is tightly bound to transferrin, cells throughout the body have receptors for transferrin-iron complexes on their surfaces.

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… dfe tuition fund
