Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: ATPase activity, coupled to transmembrane movement of substances.
There is experimental evidence that it is involved in the biological process: ommochrome biosynthetic process.
50 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: ABC transporter, conserved site; ABC transporter-like; ABC-2 type transporter; ATPase, AAA+ type, core; Pigment precursor permease.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderate expression to a trough of extremely low expression.
Peak expression observed within 06-18 hour embryonic stages, during early larval stages, at stages throughout the pupal period, in stages of adults of both sexes.
