caspP1 mutants exhibit a high rate of melanisation, found in 15% of larvae, 14% of pupae, and 17.5% of adults. This melanisation is conspicuous around internal organs such as the gut and fat body.
caspP1 flies exhibit a much higher survival rate compared to wildtype, when pricked with a needle dipped in a concentrated solution of gram-negative Esherichia coli or Erwinia carotovora.
caspP1/Df(2R)ED2457 transallelic mutants display phenotypes identical to those of caspP1 homozygotes.
caspP1 is rescued by caspUAS.Tag:MYC/Scer\GAL4da.G32
caspP1 is rescued by caspUAS.Tag:MYC/Scer\GAL4yolk
Expression of caspScer\UAS.T:Hsap\MYC, under the control of Scer\GAL4da.G32 or Scer\GAL4yolk rescues the caspP1 phenotype.
