靶點詳情

  • 功能：
    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.
  • 基因功能參考文獻：
    1. Five of these SNPs acted as cis-eQTLs, being associated with the transcription of IREB2 (rs2568494, rs16969968, rs11634351, rs6495309), PSMA4 (rs6495309) and ERCC1 (rs735482), out of 10,821 genes analyzed in lung. For these three genes, we obtained experimental evidence of differential allelic expression in lung tissue, pointing to the existence of in-cis genomic variants that regulate their transcription. PMID: 28181565
    2. Iron loading caused cell proliferation in cancer cell lines, which were less able to regulate IREB2 expression than primary bronchial epithelial cells (PBECs). Iron chelation resulted in a return of proliferation rates to baseline levels; knockdown of IREB2 had a similar effect. IRP2-positive tumours were larger and higher percentage staining related to poorer survival. PMID: 28404645

    36. it is unlikely that the iron-dependent degradation of IRP2 is mediated by haem binding to the intact 73aa-Domain, since the sequence resembling an HRM in the 73aa-Domain does not provide an axial ligand of the cofactor unless this domain is cleaved PMID: 17760563
