Title: Expression of alpha-gustducin in the circumvallate papillae of taste buds of diabetic rats.
The data suggest that gustducin is involved in signal transduction of all the tastes of sweet, umami, and bitter in the soft palate, in contrast to its limited function in the tongue.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
