The RMCE cassette of the Mi{MIC}cpxMI09455 insertion has been replaced with a Trojan-GAL4 cassette. The insertion is in a coding intron of 15 annotated transcripts of cpx (predicted to gene trap the gene) and in an intron in the 5' UTR of 4 transcripts of cpx. The insertion is also within CG9780, not in a coding intron, and is not predicted to gene trap this gene.
