Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: RNA polymerase II transcription factor binding.
There is experimental evidence that it is involved in the biological process: bristle development; regulation of eclosion; axon guidance; transcription, DNA-dependent; nervous system development; bristle morphogenesis; positive regulation of transcription, DNA-dependent; imaginal disc-derived wing morphogenesis; dendrite guidance; phagocytosis, engulfment.
36 alleles are reported.
The phenotypes of these alleles are annotated with 30 unique terms, many of which group under: organ system subdivision; synaptic neuropil subdomain; antennal segment; adult segment; adult mesothoracic segment; eo support cell; embryonic/larval neuron; postalar bristle; appendage segment; subesophageal ganglion; unguis.
It has 2 annotated transcripts and 2 annotated polypeptides.
Protein features are: LIM binding protein.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of moderate expression.
Peak expression observed within 00-18 hour embryonic stages.
