Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: tryptophan 2,3-dioxygenase activity.
There is experimental evidence that it is involved in the biological process: ommochrome biosynthetic process.
751 alleles are reported.
The phenotypes of these alleles are annotated with: eye; ocellus pigment granule; pigment cell.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Tryptophan 2,3-dioxygenase.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of extremely low expression.
Peak expression observed within 12-24 hour embryonic stages, during early larval stages, in adult male stages.
