Intestinal gene expression in different physiological conditions There is not condition-dependent expression data available for this gene.
Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: histone-lysine N-methyltransferase activity; single-stranded RNA binding; histone methyltransferase activity (H3-K4 specific); histone methyltransferase activity.
There is experimental evidence that it is involved in the biological process: histone methylation; oviposition; regulation of transcription, DNA-dependent; embryonic development via the syncytial blastoderm; chromatin-mediated maintenance of transcription; oogenesis.
45 alleles are reported.
The phenotypes of these alleles are annotated with: abdominal segment 6; haltere; abdominal segment 2; heart primordium; haltere disc; wing; imaginal disc.
It has 2 annotated transcripts and 2 annotated polypeptides.
Protein features are: AT hook, DNA-binding motif; AWS; Bromo adjacent homology (BAH) domain; Post-SET domain; SET domain; Zinc finger, FYVE/PHD-type; Zinc finger, PHD-finger; Zinc finger, PHD-type; Zinc finger, PHD-type, conserved site; Zinc finger, RING/FYVE/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, in adult female stages.
