The FRT cassette has been excised, allowing expression of the mutated fz coding sequence (containing the amino acid replacements I375A and E376A) under the control of the Act5C promoter. The fz protein sequence is tagged with EGFP.
abnormal planar polarity | adult stage, with fz21
visible, with fz21
leg, with fz21
leg joint | ectopic, with fz21
Adults carrying fzIEAA.Act5C.T:Avic\GFP-EGFP in a fz21 background have extra tarsal joints in the leg compared to wild type.
fzIEAA.Act5C.T:Avic\GFP-EGFP shows poor rescue of the wing margin phenotype of fz21 fz2C1 double homozygous clones.
