taste bud
There are four distinct tastes that the human tongue can detect. Each is identified by different taste buds, as shown in this illustration.

taste bud

(tāst)
Any of numerous sense organs on the tongues of most vertebrate animals that are sensitive to four types of taste: sweet, sour, salty, or bitter.

The 38 papers here cover structural studies of the sweetener receptor (including the genetic architecture of sweet taste, the detection of sweet stimuli and in vitro models), modeling of the sweetener receptor (including crystal structures of the sweet protein MNEI, molecular models and computational procedures), sweet taste transduction (including psychophysical studies, bitter-sweet interactions and the role of the taste buds), quantifying the reposes of sweet-sensitive taste bud cells, including perception and the acceptance of sweeteners), modulation of sweet-sensitive taste bud cell signaling, and advances in synthetic and natural non-calorie sweeteners.
They eventually located a single protein, called PKD2L1, that's in some taste bud cells but not in those that detect sweet, bitter, and umami flavors.
