Description

Nucleotides 1946-1948 (ATG), part of codons 649-650 of wild-type p are substituted by TT, resulting in a frameshift. The mutated gene encodes residues 1-648 of p, followed by an unrelated segment of 39 amino acids and an early termination codon.

Single base pair deletion within codon Q648, resulting in a frameshift. The resulting truncated protein is predicated to contain 648 amino acids from wild-type p followed by 39 additional amino acids. Also contains a silent base change in the P62 codon and a nucleotide change in the p upstream region (POU sequence CAAAT is changed to CCAAT).

Detailed Description
Statement
Reference

Mutant flies show a significant decrease in ommochrome and drosopterin pigment levels compared to wild type.

Eye colour: abnormal with reduced levels of red and brown pigment (24 and 24% of wild-type levels respectively).

p1/Df(3R)p25 flies show a reduction in pteridine (red) eye pigment levels compared to controls.

Homozygous adults are hypersensitive to paraquat.

Eye colour: dull ruby with purplish tone. 40% normal red and 33% normal brown pigment

Additional Comments
Genetic Interactions
Statement
Reference

The reduction in drosopterin pigment levels that is seen in p1 flies is not affected by HPS4W515X.

The reduction in drosopterin pigment levels seen in flies carrying wdsRNA.GMR is enhanced manyfold if they are also mutant for p1.

The mispatterning of the eye caused by expression of aosGD16463 under the control of Scer\GAL4GMR.PF is modestly enhanced in a p1 mutant background.

Expression of CG10251Scer\UAS.cFa under the control of Scer\GAL4GMR.PS does not rescue the eye colour phenotype of p1 flies.

Comments

The p1, pp and psnb alleles have been found to have identical changes in sequence, despite being reported to have arisen independently. It seems more likely that stock contamination, mislabelling, or loss occurred some time during past handling of stocks, rather than the same lesions having occurred independently three times.
