UASt regulatory sequences are fused upstream of a genomic fragment that encodes the entire ple transcription unit. A frameshift mutation (single base insertion) has been introduced near the end of exon d (an exon that is specific to the non-neural isoform). This transgene is expected to express a full-length active protein in neural tissues, but in non-neural tissues, incorporation of exon d (containing the frameshift) is expected to result in a protein that is truncated before the catalytic domain, rendering it inactive.
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.
