Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: protein binding; sequence-specific DNA binding; sequence-specific enhancer binding RNA polymerase II transcription factor activity.
There is experimental evidence that it is involved in the biological process: progression of morphogenetic furrow involved in compound eye morphogenesis; eye development; positive regulation of transcription from RNA polymerase II promoter; sensory organ development; embryonic development via the syncytial blastoderm; negative regulation of compound eye cone cell fate specification; peripheral nervous system development.
40 alleles are reported.
The phenotypes of these alleles are annotated with 19 unique terms, many of which group under: adult segment; organ system subdivision; integumentary plate; thoracic segment; non-connected developing system; external compound sense organ; postalar bristle; imaginal precursor; heart primordium; epithelial furrow.
It has 9 annotated transcripts and 9 annotated polypeptides.
Protein features are: Zinc finger, C2H2; Zinc finger, C2H2-like; Zinc finger, C2H2-type/integrase, DNA-binding.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of low expression.
Peak expression observed within 00-12 hour embryonic stages.
