Construct: Contains a cDNA encoding a major embryonic isoform of Mhc in which exon 11c has been replaced with exon 11e (exon 11e encodes the indirect flight muscle isoform converter region).
Two day old flies expressing MhcEMB-IC in a Mhc10 background show some ultrastructural deterioration of the indirect flight muscle myofibrils. These flies cannot beat their wings. These flies can jump, but achieve much shorter differences than wild-type flies.
