Summary Information
Automatically generated summary See sections below for more information	The gene Gustatory receptor 23a is referred to in FlyBase by the symbol Dmel\Gr23a (CG15396, FBgn0041248). It is a protein_coding_gene from Drosophila melanogaster. Based on sequence similarity, it is predicted to have molecular function: taste receptor activity. Based on sequence similarity, it is predicted to be involved in the biological process: sensory perception of taste. 2 alleles are reported. The phenotype of these alleles is annotated with: mesothoracic tergum. It has 2 annotated transcripts and 2 annotated polypeptides. 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 12-24 hour embryonic stages, at stages throughout the larval period, at stages throughout the pupal period, in adult male stages. Summary of FlyAtlas Anatomical Expression Data: No expression detected in any larval or adult organs/tissues. Gene sequence location is 2L:2669823..2672159.
