Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: ionotropic glutamate receptor activity; kainate selective glutamate receptor activity.
There is experimental evidence that it is involved in the biological process: neuromuscular synaptic transmission; rhythmic excitation.
10 alleles are reported.
The phenotypes of these alleles are annotated with: NMJ bouton; neuromuscular junction; embryonic/larval neuromuscular junction.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Extracellular ligand-binding receptor; Glutamate receptor, L-glutamate/glycine-binding; Ionotropic glutamate receptor; NMDA receptor.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderate expression to a trough of extremely low expression.
Peak expression observed within 06-24 hour embryonic stages, at stages throughout the larval period.
