A truncated form of D, lacking the C-terminal 75 amino acids, is expressed under the control of UASt regulatory sequences.
DΔC75.UAS/Scer\GAL4sim.PS partially rescues Dr72/Df(3L)fz-GS1a
The midline defects of Dr72/Df(3L)fz-GS1a embryos are efficiently rescued if the embryos are expressing DΔC75.Scer\UAS under the control of Scer\GAL4sim.PS.
