The RMCE cassette of the Mi{MIC}Rab3-GEFMI01069 insertion has been replaced with a Trojan-GAL4 cassette. The insertion is in a coding intron of all annotated transcripts of Rab3-GEF and is predicted to gene trap the gene. The insertion is also within CG9072, in an exon in the 5' UTR, and is not predicted to gene trap this gene.
