The RMCE cassette of the Mi{MIC}mblMI00139 insertion has been replaced with a Trojan-GAL4 cassette. The insertion is in a coding intron of mbl 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).
