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 for 14 unique biological process terms, many of which group under: anatomical structure development; multicellular organismal process; biological regulation; localization; open tracheal system development; embryonic development via the syncytial blastoderm; digestive tract development; embryonic hindgut morphogenesis; organ development; establishment or maintenance of cell polarity; gland morphogenesis.
12 alleles are reported.
The phenotypes of these alleles are annotated with 31 unique terms, many of which group under: organ system; organ system subdivision; non-connected developing system; portion of tissue; abdominal lateral pentascolopidial chordotonal organ lch5; embryonic/larval tracheal system; presumptive embryonic/larval nervous system; cuticle; gland; larval abdominal segment.
It has one annotated transcript and one annotated polypeptide.
Protein features are: BTB/POZ; BTB/POZ fold; BTB/POZ-like; Helix-turn-helix, Psq; Helix-turn-helix, Psq-like; Homeodomain-like.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of extremely low expression.
Peak expression observed within 00-18 hour embryonic stages.
