The RMCE cassette of the Mi{MIC}Hsp22MI06285 insertion has been replaced with a Trojan-GAL4 cassette. The insertion is in within the coding intron of all annotated transcripts of CG4456 and is predicted to express GAL4 in the same pattern as CG4456. The insertion is also within Hsp22, not in a coding intron, and is not predicted to gene trap this gene.
