In iron-restricted (IR) conditions, if the IRE is in the 5′-UTR, this IRP protein interaction causes a translational blockage. However, if the IRE is in the 3′-UTR, this interaction promotes mRNA stability by suppressing mRNA degradation, and the protein is synthesized [ 2 ]. grant henry medlock https://wackerlycpa.com
