Protein Structure

UniProt Annotation

Function

Putative taste receptor. TAS1R1/TAS1R3 responds to the umami taste stimulus (the taste of monosodium glutamate). Sequence differences within and between species can significantly influence the selectivity and specificity of taste responses. {ECO:0000269PubMed:11917125}.

Subcellular Localization

Cell membrane; Multi-pass membrane protein.
