Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: glucose-6-phosphate isomerase activity.
It is reported to be involved in the biological process: gluconeogenesis; glycolysis.
21 alleles are reported.
No phenotypic data is available.
It has 3 annotated transcripts and 3 annotated polypeptides.
Protein features are: Phosphoglucose isomerase (PGI); Phosphoglucose isomerase, C-terminal; Phosphoglucose isomerase, conserved site.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of moderately high expression.
Peak expression observed within 18-24 hour embryonic stages, at stages throughout the larval period, during late pupal stages, in stages of adults of both sexes.
