MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Sweet, bitter, and umami tastes are transmitted from taste receptors by a specific guanine nucleotide binding protein. The protein encoded by this gene is the alpha subunit of this heterotrimeric G protein, which is found not only in the oral epithelium but also in gut tissues. Variations in this gene have been linked to metabolic syndrome. [provided by RefSeq, Dec 2015]
PHENOTYPE: Homozygous mutation of this gene results in abnormal taste sensitivity. Mice show reduced behavioral and electrophysiological responses to bitter, sweet, and unami compounds. [provided by MGI curators]
