UAS regulatory sequences drive expression of sog which has a mutation of a conserved tryptophan residue to alanine in all four cysteine repeat domains.
visible, with Scer\GAL4Bx-MS1096
wing vein, with Scer\GAL4Bx-MS1096
Expression of sogA1234.Scer\UAS under the control of Scer\GAL4Bx-MS1096 results in a loss of wing veins.
