Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: hormone activity.
There is experimental evidence that it is involved in the biological process: cuticle pigmentation; chitin-based cuticle tanning; regulation of adult chitin-containing cuticle pigmentation; imaginal disc-derived wing morphogenesis.
9 alleles are reported.
The phenotypes of these alleles are annotated with: adult thorax; adult cuticle; adult abdomen; wing; posterior scutellar bristle.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Cystine knot, C-terminal; DAN.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderate expression to a trough of no expression detected.
Peak expression observed within 12-24 hour embryonic stages, during early larval stages, during late pupal stages.
