Amino acid replacement: D88A.
UASt regulatory sequences drive expression of a mutated form of arm, which is tagged at the N-terminal end with Tag:FLAG.
Expression of armD88A.Scer\UAS.T:Zzzz\FLAG under the control of Scer\GAL4mat.αTub67C.T:Hsim\VP16 slightly delays the execution of apoptosis in th109.07 embryos, but apoptosis is otherwise unimpaired in the double mutant embryos.
