Imprecise excision of the progenitor insertion, P{GT1}Sulf1GT-000656 results in a deletion which removes exons 4-10 of Sulf1 with loss of most of the protein coding sequence including part of the catalytic domain of Sulf1.
The wings of mutant adults are larger than normal and show defects in apposition of the two wing surfaces. There is a mild broadening of the spacing between the L3 and L4 veins compared to wild type. Supernumerary chemosensory and mechanosensory bristles are observed on the anterior wing margin.
Wings carrying homozygous clones in the anterior compartment show broadening of the spacing between veins L3 and L4 and also show defects in the positioning of the L2 vein. Wings carrying homozygous clones in the posterior compartment of the wing show a narrowing of the spacing between veins L3 and L4 and defects in the positioning of wing vein L2.
Sulf1ΔP1 and Sulf1ΔP1/Df(3R)sbd26 mutant adults both display defects in wing margin bristles. An increase in the number of chemosensory and mechanosensory bristles on the anterior wing margin is evident. Ectopic mechanosensory bristles which have shifted more posterior to their normal position are also observed.
Sulf1ΔP1 third instar larval wing discs exhibit an increase in the number of sensory organ precursors. An irregular, borader distribution of the SOPs is observed in the disc.

The increased division of intestinal stem cells in the adult posterior midgut during normal homeostasis characteristic for Sulf1KO;Cherry/Sulf1ΔP1 mutants can be suppressed by expression of any of the following: Stat92EdsRNA.Scer\UAS, EgfrDN.Scer\UAS.cBa or ptcScer\UAS.cJa under the control of Scer\GAL4NP6267 (using tub-Gal80[ts] to limit the time of expression to adulthood).
Hs6std770 suppresses the increased chemosensory bristle phenotype observed at the anterior dorsal wing margin of Sulf1ΔP1 mutant animals.
dallygem, Sulf1ΔP1 mutant animals display the same reduced number of chemosensory and mechanosensory bristles at the anterior dorsal wing margin as dallygem single mutants.
