Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: 6-pyruvoyltetrahydropterin synthase activity.
There is experimental evidence that it is involved in the biological process: pteridine biosynthetic process.
20 alleles are reported.
The phenotype of these alleles is annotated with: pigment cell.
It has one annotated transcript and one annotated polypeptide.
Protein features are: 6-carboxy/6-pyruvoyl tetrahydropterin synthase; 6-pyruvoyl tetrahydropterin synthase, cysteine active site; 6-pyruvoyl tetrahydropterin synthase, histidine active site; 6-pyruvoyl tetrahydropterin synthase-related.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of moderate expression.
Peak expression observed within 00-06 hour embryonic stages, during late larval stages.
