Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: olfactory receptor activity.
There is experimental evidence that it is involved in the biological process: olfactory behavior; detection of chemical stimulus involved in sensory perception of smell.
4 alleles are reported.
The phenotype of these alleles is annotated with: adult olfactory receptor neuron Or42a.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Olfactory receptor, Drosophila.
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 within 00-06 and 18-24 hour embryonic stages.
