Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: protein binding; sequence-specific DNA binding; sequence-specific enhancer binding RNA polymerase II transcription factor activity; DNA binding.
There is experimental evidence that it is involved in the biological process: oenocyte development; brain development.
63 alleles are reported.
The phenotypes of these alleles are annotated with 55 unique terms, many of which group under: organ system subdivision; adult segment; organ system; cephalopharyngeal skeleton; thoracic segment; antennal segment; presumptive embryonic/larval nervous system; appendage segment; multi-cell-component structure; pharyngeal sclerite.
It has 3 annotated transcripts and 3 annotated polypeptides.
Protein features are: Homeobox; Homeobox, conserved site; Homeodomain-like; Homeodomain-related; PBX.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of moderately high expression.
Peak expression observed at stages throughout embryogenesis, during late larval stages, during early pupal stages.
