The RMCE cassette of the Mi{MIC}CG31368MI10113 insertion has been replaced with a Trojan-GAL4 cassette. The insertion is in a coding intron of both annotated transcripts of CG31368 and is predicted to gene trap the gene. The insertion may also affect the expression of the mthl5 gene, because it is upstream of this gene and within 500 bp of its 5' end.
