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.
An electronic pipeline based on InterPro domains suggests that it has the molecular function: extracellular-glutamate-gated ion channel activity; ionotropic glutamate receptor activity.
The biological processes in which it is involved are not known.
4 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 very low expression to a trough of extremely low expression.
Peak expression observed at stages throughout embryogenesis, at stages throughout the larval period, at stages throughout the pupal period, in stages of adults of both sexes.
