Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: IMP dehydrogenase activity.
There is experimental evidence that it is involved in the biological process: axon guidance; phagocytosis, engulfment.
83 alleles are reported.
The phenotypes of these alleles are annotated with: macrochaeta; pigment cell.
It has 3 annotated transcripts and 3 annotated polypeptides.
Protein features are: Aldolase-type TIM barrel; Cystathionine beta-synthase, core; IMP dehydrogenase; IMP dehydrogenase / GMP reductase, conserved site; IMP dehydrogenase-related; IMP dehydrogenase/GMP reductase.
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 00-06 hour embryonic stages, at stages throughout the larval period, during early pupal stages, in adult female stages.
