A set of transgenic insertion stocks containing a gene trap cassette, derived from Mi{MIC} insertions in coding introns using Recombinase-Mediated Cassette Exchange (RMCE); see http://flypush.imgen.bcm.tmc.edu/pscreen/technique.html. The gene trap cassette contains a Trojan GAL4 exon composed of a splice acceptor, T2A peptide, GAL4 coding sequence and an Hsp70 transcription termination signal. When inserted in a coding intron in the correct orientation, the cassette should result in truncation of the trapped gene product and expression of GAL4 under the control of the regulatory sequences of the trapped gene. Each insertion line contains one of three versions of the cassette (Mi{Trojan-GAL4.0}, Mi{Trojan-GAL4.1} or Mi{Trojan-GAL4.2}), depending on the frame required to generate a gene trap.
MI05757-TG4.un
The RMCE cassette of the Mi{MIC}CG43427MI05757 insertion has been replaced with a Trojan-Gal4 cassette. The insertion is in the coding intron of five annotated transcripts of CG43427, one of which is a phase 1 intron and four of which are phase 0 introns. It has not been determined which Trojan exon phase construct is inserted and therefore which transcripts are trapped and driving expression of Scer\GAL4.
