A frameshift mutation is introduced by using site-directed mutagenesis to remove a base at the end of hypoderm-specific exon e resulting in a truncation and an inactive enzyme.
Scer\GAL4ple.PF, pleFStrunc.UAS, Scer\GAL4Ddc.PL fails to rescue ple2
Expression of pleFStrunc.Scer\UAS under the control of both Scer\GAL4ple.PF and Scer\GAL4Ddc.PL fails to rescue the embryonic lethality normally found in ple2 mutants.
When transcribed, pleFStrunc.Scer\UAS expresses active ple in neural tissues.
