Three copies of Tag:HA are inserted after the codon for T140 in a genomic fragment of osk. This places the epitope tag just after the start of the short isoform of osk (which would begin at M139).
oskTag:HA rescues oskA87/Df(3R)osk
Fully rescues osk mutants.Flies rescued with oskT:Ivir\HA1 are viable and fertile.
Embryos from oskA87/Df(3R)osk mothers expressing oskM1R.Δ40-84.Δ196-423.T:Ivir\HA1 display normal segmentation.
