Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: odorant binding.
Based on sequence similarity, it is predicted to be involved in the biological process: sensory perception of chemical stimulus.
One allele is reported.
No phenotypic data is available.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Insect pheromone/odorant binding protein PhBP; Pheromone/general odorant binding protein, PBP/GOBP; Pheromone/general odorant binding protein, PBP/GOBP, domain.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of no expression detected.
Peak expression observed in adult male stages.
