UASt regulatory sequences drive expression of a mutated form of Ser which lacks amino acid residues 532-574 and contains the amino acid replacement I575L.
visible, with Scer\GAL4Ser.PGF
wing margin, with Scer\GAL4Ser.PGF
wing vein, with Scer\GAL4Ser.PGF
Expression of SerhydroΔ6.Scer\UAS under the control of Scer\GAL4Ser.PGF results in a notched wing margin and wing vein deltas.
