DESCRIPTION

Also known as IREB2_HUMAN, IREB2. RNA-binding protein that binds to iron-responsive elements (IRES), which are stem-loop structures found in the 5'-UTR of ferritin, and delta aminolevulinic acid synthase mRNAs, and in the 3'-UTR of transferrin receptor mRNA. Binding to the IRE element in ferritin results in the repression of its mRNA translation. Binding of the protein to the transferrin receptor mRNA inhibits the degradation of this otherwise rapidly degraded mRNA. Interacts with RBCK1 isoform 1 and isoform 2 only in iron-rich conditions (PubMed:12629548). Interacts (when associated with the 4Fe-4S) with FBXL5 (PubMed:19762596, PubMed:19762597). Interacts with CIAO1 and CIAO2A (PubMed:23891004).
