UASp regulates expression of the PI isoform of smash (amplified from cDNA clone GH26442) in which all six Y residues (potential Src phosphorylation sites) are mutated to F, and tagged at the N-terminus with GFP.
smashPI.YmultiF.UASp.GFP/Scer\GAL4Act5C.PI rescues Df(3R)smash35
Expression of smashPI.YmultiF.UASp.GFP under the control of Scer\GAL4Act5C.PI rescues the partial lethality observed in Df(3R)smash35 homozygous animals.
