UAS regulatory sequences drive expression of TBSV\P19 which is tagged with Tag:FLAG.
non-enhancer of variegation, with Scer\GAL4Act5C.PU
non-suppressor of variegation, with Scer\GAL4Act5C.PU
Expression of Zzzz\p19Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4Act5C has no effect on the position effect variegation of the Sb1 allele that is seen in the T(2;3)SbV chromosome.
