Three base pair insertion in CtBP.
CtBPN148PY, Scer\GAL4rn-GAL4-5, egrUAS.cUa has visible | adult stage phenotype
CtBPN148PY, Scer\GAL4rn-GAL4-5, egrUAS.cUa has wing | ectopic phenotype
Expression of egrUAS.cUa under the control of Scer\GAL4rn-GAL4-5 (with tub-Gal80[ts] restricting expression to third instar larvae) in CtBPN148PY background leads to ectopic wings compared to control adults.
