UAS regulates expression of an inverted repeat (head-to-head orientation) of a 500-bp-long cDNA fragment of the N-terminal region of the ORF, designed to induce RNAi-mediated degradation of the target.
Scer\GAL4Bx-MS1096 or Scer\GAL4A9-mediated expression results in thick wing veins.
Scer\GAL4sd-SG29.1-mediated expression results in posterior crossvein deletion.
