A 90bp nucleotide region of the nos 3'UTR (the "TCE" or "translational control element") has been inserted into the αTub84B 3'UTR sequences.
lethal, with Scer\GAL4h-1J3
lethal, with Scer\GAL4how-24B
partially lethal - majority die, with Scer\GAL4HD34A
Expression of nosαTub84B.3'UTR.nos+2.Scer\UAS in the dorsal pouch epithelium, under the control of Scer\GAL4HD34A, causes lethality in ~35% of flies.
