Gene

TAS1R3

TAS1R3 encodes taste receptor type 1 member 3, a G-protein-coupled receptor subunit expressed in taste bud cells that pairs with TAS1R2 to form the sweet-taste receptor and with TAS1R1 to form the umami-taste receptor. Variants in TAS1R3 alter sensitivity to sweet-tasting compounds and, in this dataset, are linked to variation in how strongly a person perceives sweet (and, via shared taste-signaling pathways, bitter) flavors.
