The FRT cassette has been excised, allowing the Ubx promoter to drive expression of a coding cassette composed of GAL4 and lacZ (the two coding regions are separated by an internal ribosome entry site).
Used for clonal analysis in wing disc; EcollacZ serves as marker for ScerGAL4-expressing cells.
Exists in clones, not reported as germ-line transmitted. Scer\GAL4 and Ecol\lacZ are expressed from a dicistronic transcript in this construct.
