UASt regulatory sequences drive expression of amino acids 270-805 of fu. The protein is tagged with Tag:polyHis.
Expression of futail.Scer\UAS.T:Zzzz\His6 under the control of Scer\GAL4ap-md544 results in severe proximal and distal fusions of wing veins L3 and L4. At the wing margin, double row bristles extend beyond vein 3 to vein 4.
Flies expressing futail.Scer\UAS.T:Zzzz\His6 under the control of Scer\GAL4dpp.PU show proximal fusions of wing veins L3 and L4 and have ectopic wing veins distally. At the wing margin, double row bristles extend beyond vein 3 to vein 4.
