The RMCE cassette in the Mi{MIC}CG17841MI13728 insertion has been replaced with a 'Double Header' (DH) trapping cassette (contains two independent trapping modules oriented in opposite directions). The cassette is in 'protein-trap' orientation relative to CG17841, which is predicted to result in the CG17841 coding sequence being tagged with a EGFP-Tag:CALI(TC)-Tag:StrepII-Tag:CS(TEVp)-3xTag:FLAG multi-tag cassette.
