Imprecise excision of the progenitor insertion, resulting in a 711bp deletion that removes the entire tsu coding sequence.
tsu[+], tsuΔ18, Scer\GAL4GMR.PF is an enhancer of increased cell death phenotype of Cln3UAS.cTa, Scer\GAL4en-e16E
Df(2R)BSC600/PymSH1616, tsu[+]/tsuΔ18 has lethal phenotype
tsu[+]/tsuΔ18, Scer\GAL4GMR.PF is an enhancer of eye phenotype of Cln3UAS.cTa, Scer\GAL4GMR.PF
A tsuΔ18 heterozygous background enhances the cln3Scer\UAS.cTa overexpression eye phenotype.
