Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
There is experimental evidence that it has the molecular function: taste receptor activity; sweet taste receptor activity.
There is experimental evidence that it is involved in the biological process: detection of chemical stimulus involved in sensory perception of taste; response to trehalose stimulus; proboscis extension reflex; sensory perception of sweet taste; sensory perception of taste.
72 alleles are reported.
The phenotypes of these alleles are annotated with: large labellar taste bristle; labellar taste bristle.
It has one annotated transcript and one annotated polypeptide.
Protein features are: Trehalose receptor.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of low expression to a trough of no expression detected.
Peak expression observed during early pupal stages.
