The RMCE cassette of the Mi{MIC}NosMI15126 insertion has been replaced with a Trojan-GAL4 cassette. The insertion is in a coding intron of Nos and is predicted to gene trap the gene. (Note that if this gene has multiple transcripts, only those where the insertion is in a coding intron are predicted to be trapped). The insertion may also affect the expression of the CG6508 gene, because it is upstream of this gene and within 500 bp of its 5' end.
