Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: protein binding; protein homodimerization activity; olfactory receptor activity.
There is experimental evidence that it is involved in the biological process: olfactory behavior; response to pheromone; behavioral response to ethanol.
26 alleles are reported.
The phenotypes of these alleles are annotated with: olfactory receptor neuron; antennal sense organ.
It has 2 annotated transcripts and 2 annotated polypeptides.
Protein features are: Olfactory receptor, Drosophila.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderate expression to a trough of no expression detected.
Peak expression observed during late pupal stages, in adult male stages.
