UASt regulatory sequences drive expression of Dark coding sequences, with a mutated caspase site (carries the amino acid replacement D1292A), with 8xTag:polyHis at the N-terminal end and 6xTag:MYC tags at the carboxy terminal end.
Expression of ArkScer\UAS.T:Zzzz\His6,T:Hsap\MYC in hemocytes, under the control of Scer\GAL4Hml.PG almost completely restores apoptosis levels after Smac mimetic treatment.
DarkD1292A.UAS.Tag:polyHis,Tag:MYC/Scer\GAL4C833 partially rescues Dark82
DarkD1292A.UAS.Tag:polyHis,Tag:MYC partially rescues Dark82
Scer\GAL4c81/DarkD1292A.UAS.Tag:polyHis,Tag:MYC fails to rescue Dark82
Adult Ark82 flies rescued to viability by expression of ArkB1292A.Scer\UAS.T:Zzzz\His6,T:Hsap\MYC under the control of Scer\GAL4unspecified display split thorax phenotypes and bristle abnormalities in the notum.
Surprisingly, in the absence of any Scer\GAL4 driver, `leaky' expression of ArkB1292A.Scer\UAS.T:Zzzz\His6,T:Hsap\MYC partially rescues Ark82 lethality.
