Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: taste receptor activity.
There is experimental evidence that it is involved in the biological process: immune response; melanization defense response; feeding behavior.
5 alleles are reported.
No phenotypic data is available.
It has 5 annotated transcripts and 5 annotated polypeptides.
Protein features are: 7TM chemoreceptor.
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 12-24 hour embryonic stages, at stages throughout the larval period, during early pupal stages, in adult male stages.
