Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: DNA binding.
There is experimental evidence that it is involved in the biological process: compound eye photoreceptor cell differentiation; compound eye development; compound eye morphogenesis.
8 alleles are reported.
The phenotypes of these alleles are annotated with: eye; antenna; ommatidium.
It has 2 annotated transcripts and 2 annotated polypeptides.
Protein features are: Homeobox; Homeodomain-like; Homeodomain-related.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderate expression to a trough of very low expression.
Peak expression observed at stages throughout embryogenesis, during late larval stages, at stages throughout the pupal period, in adult male stages.
