UAS regulatory sequences drive expression of the C-terminal 141 amino acid residues of BEAF-32 which are tagged at the N-terminal end with a Tag:HA tag and a Tag:NLS(SV40-largeT) nuclear localisation signal. Encodes a dominant negative form of BEAF-32.
Expression of BEAF-32BID.UAS.Tag:HA,Tag:NLS(SV40-largeT) under the control of Scer\GAL4GMR.long causes an increase in the proportion of pale R8 photoreceptors and a reciprocal decrease in the proportion of yellow R8 photoreceptors, compared to controls.
Expression of BEAF-32BID.Scer\UAS.T:Ivir\HA1,T:SV40\nls2 under the control of Scer\GAL4ey.PH results in a rough eye phenotype.
Expression of BEAF-32BID.Scer\UAS.T:Ivir\HA1,T:SV40\nls2 under the control of Scer\GAL4da.G32 can result in lethality, depending on the P{UAS-BEAF-32.BID} insertion line used (the severity of the phenotype depends on the level of expression from the transgene).
Expression of BEAF-32BID.Scer\UAS.T:Ivir\HA1,T:SV40\nls2 under the control of Scer\GAL4ey.PH results in a rough eye phenotype. The severity of the phenotype is increased if the flies carry two copies of BEAF-32BID.Scer\UAS.T:Ivir\HA1,T:SV40\nls2.
Third instar larvae expressing BEAF-32BID.Scer\UAS.T:Ivir\HA1,T:SV40\nls2 under the control of Scer\GAL4AB1 or Scer\GAL434B have smaller salivary glands than normal which are easily fragmented and lack the characteristic well-defined banding pattern.
The mitotic index in the brain is not altered compared to wild type in larvae expressing BEAF-32BID.Scer\UAS.T:Ivir\HA1,T:SV40\nls2 under the control of Scer\GAL4c768. No defects in chromosome condensation are seen, and there is no premature sister-chromatid separation, aneuploidy or anaphase problems. The size of the brain is normal in these larvae.
BEAF-32BID.UAS.Tag:HA,Tag:NLS(SV40-largeT), Scer\GAL4ey.PH has visible phenotype, enhanceable by ftz[+]/ftz3
BEAF-32BID.UAS.Tag:HA,Tag:NLS(SV40-largeT), Scer\GAL4ey.PH has visible phenotype, non-enhanceable by Dref[+]/DrefKG09294
BEAF-32BID.UAS.Tag:HA,Tag:NLS(SV40-largeT), Scer\GAL4ey.PH has visible phenotype, non-enhanceable by mle[+]/mle9
BEAF-32BID.UAS.Tag:HA,Tag:NLS(SV40-largeT), Scer\GAL4ey.PH has eye phenotype, enhanceable by ftz[+]/ftz3
BEAF-32BID.UAS.Tag:HA,Tag:NLS(SV40-largeT), Scer\GAL4ey.PH has eye phenotype, non-enhanceable by Dref[+]/DrefKG09294
BEAF-32BID.UAS.Tag:HA,Tag:NLS(SV40-largeT), Scer\GAL4ey.PH has eye phenotype, non-enhanceable by mle[+]/mle9
The rough eye phenotype of flies expressing BEAF-32BID.Scer\UAS.T:Ivir\HA1,T:SV40\nls2 under the control of Scer\GAL4ey.PH is enhanced by ftz3/+, but is not enhanced by either DrefKG09294/+ or mle9/+.
BEAF-32BID.UAS.Tag:HA,Tag:NLS(SV40-largeT) is partially rescued by BEAF-32+t5/Scer\GAL4ey.PH
BEAF-32BID.UAS.Tag:HA,Tag:NLS(SV40-largeT) is partially rescued by BEAF-32+t5/Scer\GAL4AB1
The rough eye phenotype of flies expressing BEAF-32BID.Scer\UAS.T:Ivir\HA1,T:SV40\nls2 under the control of Scer\GAL4ey.PH is almost completely rescued by BEAF-32+t5.
