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: olfactory learning; ectoderm development; learning or memory; cell proliferation; imaginal disc-derived wing vein morphogenesis; wing disc anterior/posterior pattern formation; wing disc dorsal/ventral pattern formation; imaginal disc-derived wing morphogenesis; midgut development.
111 alleles are reported.
The phenotypes of these alleles are annotated with 21 unique terms, many of which group under: organ system subdivision; organ system; adult segment; presumptive embryonic/larval nervous system; external compound sense organ; presumptive embryonic/larval peripheral nervous system; non-connected developing system; primordium; adult mesothoracic segment; embryonic head; midgut constriction; podocyte; multi-cell-component structure; spiracle.
It has 4 annotated transcripts and 4 annotated polypeptides.
Protein features are: Zinc finger, C2H2; Zinc finger, C2H2-like; Zinc finger, C2H2-type/integrase, DNA-binding; Zinc finger, U1-type.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderate expression to a trough of low expression.
Peak expression observed at stages throughout embryogenesis, at stages throughout the larval period, at stages throughout the pupal period, in stages of adults of both sexes.
