Polytene chromosomes normal.
Insertion of gypsy element 6kb upstream of the 5'-most identified exon, in orientation opposite to that of cut. The gypsy element has a 129bp deletion that extends from the 1st to the 6th octamer repeat (proposed to interact with the su(Hw) product), spanning total of 5 repeats.
Insertion of gypsy element at nucleotide position -48.
DNA coordinates (FBrf0042060) (0 is gypsy site in ct6): +70.8 to +73.3

ctK mutants heterozygous for pds5e3 exhibit a slightly increased number of wing margin nicks compared to ctK heterozygotes, although this is not significantly different from that seen in ctK single mutants.
Expression of wgScer\UAS.cLa under the control of Scer\GAL4C96 suppresses the loss of wing blade tissue, including the slender recurved chemosensory wing margin bristles, seen in ctK flies, but does not rescue the loss of the stout mechanosensory wing margin bristles.
Expression of mod(mdg4)Scer\UAS.cGa or mod(mdg4)ΔQ.Scer\UAS under the control of Scer\GAL4Act5C in a ctK,mod(mdg4)ul mutant background suppresses the effect that mod(mdg4)ul has on ctK wings, and the wings that form lack regions of the wing margin and are similar to ctK wings.
