Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: sequence-specific DNA binding.
There is experimental evidence that it is involved in the biological process: compound eye development.
30 alleles are reported.
The phenotypes of these alleles are annotated with: embryonic optic lobe primordium; embryonic head; cuticle; extended germ band embryo; optic lobe; presumptive embryonic/larval central nervous system; denticle belt.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Homeobox; Homeobox, conserved site; Homeobox, eukaryotic; Homeodomain-like; Homeodomain-related.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of no expression detected.
Peak expression observed within 00-06 hour embryonic stages.
