UAS regulatory sequences drive expression of Mmus\Sfrp1 coding sequences fused in frame with a C-terminal Tag:MYC tag.
Ectopic expression of Mmus\Sfrp1Scer\UAS.T:Hsap\MYC in the posterior compartment of the wing imaginal disc under the control of Scer\GAL4hh-Gal4 interferes with dorsoventral and anterior-posterior patterning and results in wing notches in the posterior wing margin.
