WebMay 11, 2010 · IREs are cis-acting regulatory motifs present in mRNAs that encode proteins involved in iron metabolism. They function as binding sites for two related trans-acting factors, namely the IRP-1 and -2. Among cis-acting RNA regulatory elements, the IRE is one of the best characterized. It is defined by a combination of RNA sequence and structure. Webdel ferro, e quindi il sistema IRP/IRE permette un controllo coordinato tra loro delle principali proteine coinvolte nel mantenimento dell’omeostasi del fer-ro. Tali proteine …
