Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: sequence-specific DNA binding transcription factor activity.
There is experimental evidence that it is involved in the biological process: embryo development; brain development; brain segmentation.
37 alleles are reported.
The phenotypes of these alleles are annotated with 21 unique terms, many of which group under: organ system subdivision; organ system; nervous system; adult segment; presumptive embryonic/larval nervous system; cephalopharyngeal skeleton; commissure; multi-cell-component structure; portion of tissue; podocyte; frontal connective; antennal segment.
It has 2 annotated transcripts and 2 annotated polypeptides.
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 moderate expression to a trough of extremely low expression.
Peak expression observed within 12-24 hour embryonic stages, during early larval stages.
