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. WebJan 1, 2024 · Highlights. IRPs/IRE system, as a non-iron factor, plays an increasingly important role in neurodegenerative disorders.
