UASt regulates expression of a Hsap\ACO1 cDNA containing a Cys437Ser substitution, rendering the protein constitutively active. The expressed protein is capable of inhibiting the translation of mRNAs with a 5' iron response element (IRE) in vivo.
lethal, with Scer\GAL4arm.PS
Scer\GAL4arm.PS-mediated expression results in near 100% lethality.
