Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: receptor binding; histone methyltransferase activity (H3-K4 specific); transcription coactivator activity.
There is experimental evidence that it is involved in the biological process: progression of morphogenetic furrow involved in compound eye morphogenesis; histone methylation; compound eye development; positive regulation of transcription, DNA-dependent.
9 alleles are reported.
The phenotypes of these alleles are annotated with: eye; ommatidium; morphogenetic furrow.
It has 2 annotated transcripts and 2 annotated polypeptides.
Protein features are: FY-rich, C-terminal; FY-rich, C-terminal subgroup; FY-rich, N-terminal; FY-rich, N-terminal subgroup; Post-SET domain; SET domain; Zinc finger, PHD-type.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of low expression.
Peak expression observed within 00-12 hour embryonic stages.
