Expresses an osk transgene from a genomic fragment that includes the 5' extended UTR. The start codon for translation of isoform long-osk, M1, is mutated (as in oskM1R). Because long-osk is not produced by the transgene, mutations that lie between the start codons for long-osk and short-osk will only alter the mRNA sequence, and not the protein coding sequence. The transgene includes a 3xHA epitope tag, inserted after amino acid residue T140. The short-osk start codon is M139. Carries inversion 121-182 in the extended 5' UTR of osk.
Segmentation defects are observed in embryos from oskA87/Df(3R)osk mothers expressing oskM1R.INV121-182.T:Ivir\HA1.
