UAS regulatory sequences drive expression of a mutated form of sog which lacks cysteine repeat domains CR1 through CR2.
visible, with Scer\GAL4Bx-MS1096
wing vein, with Scer\GAL4Bx-MS1096
Expression of sogCR3-4.Scer\UAS under the control of Scer\GAL4Bx-MS1096 results in mild truncation of the wing veins although patterning of the anterior/posterior axis in the wing is normal.
