Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
It is reported to have molecular function: DNA binding; sequence-specific DNA binding transcription factor activity.
There is experimental evidence that it is involved in the biological process: motor axon guidance; brain development; brain segmentation; peripheral nervous system development.
29 alleles are reported.
The phenotypes of these alleles are annotated with 37 unique terms, many of which group under: organ system subdivision; organ system; adult segment; larval abdominal segment; non-connected developing system; sensory cluster; portion of tissue; adult; peripheral nervous system; region of integument.
It has 2 annotated transcripts and 2 annotated polypeptides.
Protein features are: Homeobox; Homeobox, conserved site; Homeodomain-like; Homeodomain-related; Lambda repressor-like, DNA-binding; POU; POU-specific; Transcription factor, homeobox/POU.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of very low expression.
Peak expression observed within 06-18 hour embryonic stages.
