shf cDNA (GH27042) from which the 'EGF' repeats domain has been deleted, is under the control of UASt sequences.
Scer\GAL4en-e16E/shfδEGF.UAS partially rescues shfx33
Expression of shfδEGF.Scer\UAS under the control of Scer\GAL4en-e16E weakly rescues the wing vein phenotypes seen in shfx33/Y mutants.
