UASt regulatory sequences drive expression of the N-terminal portion of Ser (through to the end of EGF-like repeat 6), in which amino acid residues 391-490 (EGF-like repeat 4) have been deleted.
visible, with Scer\GAL4Ser.PGF
wing margin, with Scer\GAL4Ser.PGF
Expression of SerNterm6Del4.Scer\UAS under the control of Scer\GAL4Ser.PGF results in a mild wing nicking phenotype.
