The RMCE cassette of the Mi{MIC}FsMI04308 insertion has been replaced with a EGFP-FlAsH-StrepII-TEV-3xFlag multi-tag cassette. The insertion is in a coding intron of Fs and is predicted to protein trap the gene. The insertion is also within CG8079 and is not predicted to protein trap this gene.
FsMI04308-TG4.1/FsMI04308-GFSTF.1 adult males show a progressive decrease in hub cell number in the testes.
