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.
Based on sequence similarity, it is predicted to have molecular function: extracellular-glutamate-gated ion channel activity.
The biological processes in which it is involved are not known.
3 alleles are reported.
No phenotypic data is available.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Ionotropic glutamate receptor.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of low expression to a trough of very low expression.
Peak expression observed within 12-18 embryonic stages, during late larval stages, at stages throughout the pupal period.
