Based on sequence similarity, it is predicted to be involved in the biological process: sensory perception of taste.
One allele is reported.
No phenotypic data is available.
It has one annotated transcript and one annotated polypeptide.
Protein features are: 7TM chemoreceptor.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of extremely low expression to a trough of no expression detected.
Peak expression observed within 00-06 and 12-24 hour embryonic stages, at stages throughout the larval period.
