Taste perception: how sweet it is (to be transcribed by you)

Curr Biol. 2009 Aug 11;19(15):R655-6. doi: 10.1016/j.cub.2009.06.050.


In mammals, sweet taste is mediated largely by a single receptor. New work shows that polymorphisms in the promoter region of one subunit contribute to variation in sweet perception in the human population.
