[https://www.uniprot.org/uniprot/ACOHC_RABIT ACOHC_RABIT] Bifunctional iron sensor that switches between 2 activities depending on iron availability (By similarity). Iron deprivation, promotes its mRNA binding activity through which it regulates the expression of genes involved in iron uptake, sequestration and utilization (PubMed:17185597). Binds to iron-responsive elements (IRES) in the untranslated region of target mRNAs preventing for instance the translation of ferritin and aminolevulinic acid synthase and stabilizing the transferrin receptor mRNA (PubMed:17185597).[UniProtKB:P21399]<ref>PMID:17185597</ref> Conversely, when cellular iron levels are high, binds a 4Fe-4S cluster which precludes RNA binding activity and promotes the aconitase activity, the isomerization of citrate to isocitrate via cis-aconitate.[UniProtKB:P21399] | |||
