Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Its molecular function is unknown.
There is experimental evidence that it is involved in the biological process: melanin biosynthetic process; cuticle pigmentation; male courtship behavior, veined wing extension; male mating behavior; developmental pigmentation.
1031 alleles are reported.
The phenotypes of these alleles are annotated with 42 unique terms, many of which group under: adult segment; organ system subdivision; sensillum; adult mesothoracic segment; antennal segment; appendage segment; cephalopharyngeal skeleton; somatic cell; wing hair; adult cuticle.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Major royal jelly; Major royal jelly-related; Six-bladed beta-propeller, TolB-like.
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 late pupal stages.
