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: kainate selective glutamate receptor activity.
There is experimental evidence that it is involved in the biological process: sensory perception of smell.
13 alleles are reported.
The phenotype of these alleles is annotated with: sensillum coeloconicum of antennal segment 3.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Glutamate receptor, L-glutamate/glycine-binding; Ionotropic glutamate receptor; NMDA receptor.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very low expression to a trough of no expression detected.
Peak expression observed in adult male stages.
