  2. Taste receptor - Wikipedia

    en.wikipedia.org/wiki/Taste_receptor

    The sweet taste receptor is one of the taste receptors where the function has been lost. In mammals, the predominant sweet taste receptor is the Type 1 taste receptor Tas1r2/Tas1r3. [ 46 ] Some mammalian species such as cats and vampire bats have shown inability to taste sweet. [ 46 ]

  3. TAS1R2 - Wikipedia

    en.wikipedia.org/wiki/TAS1R2

    T1R2 - Taste receptor type 1 member 2 is a protein that in humans is encoded by the TAS1R2 gene. [5] The sweet taste receptor is predominantly formed as a dimer of T1R2 and T1R3 by which different organisms sense this taste. In songbirds, however, the T1R2 monomer does not exist, and they sense the sweet taste through the umami taste receptor ...

  4. Sweetness - Wikipedia

    en.wikipedia.org/wiki/Sweetness

    To depolarize the cell, and ultimately generate a response, the body uses different cells in the taste bud that each express a receptor for the perception of sweet, sour, salty, bitter or umami. Downstream of the taste receptor, the taste cells for sweet, bitter and umami share the same intracellular signalling pathway. [36]

    Typically, sweet receptors are only triggered by sweet things like sugar. But miraculin changes the receptor's sensitivity, making it activate in response to acids instead of sugar.

  6. TAS1R3 - Wikipedia

    en.wikipedia.org/wiki/TAS1R3

    Taste receptor type 1 member 3 is a protein that in humans is encoded by the TAS1R3 gene. [5] [6] The TAS1R3 gene encodes the human homolog of mouse Sac taste receptor, a major determinant of differences between sweet-sensitive and -insensitive mouse strains in their responsiveness to sucrose, saccharin, and other sweeteners.

    "Cats are unable to taste sweet things like sugar," confirms Dr. MacMillan. "The genes Tas1r2 and Tas1r3 are responsible for the coding of the sweet taste receptor proteins in many mammals ...

  8. Taste bud - Wikipedia

    en.wikipedia.org/wiki/Taste_bud

    The type II taste bud cells make up about another third of the cells in the taste bud and express G-protein coupled receptors that are associated with chemoreception. They usually express either type 1 or type 2 taste receptors, but one cell might detect different stimuli, such as umami and sweetness. [5]

  9. TAS1R1 - Wikipedia

    en.wikipedia.org/wiki/TAS1R1

    The nonselective cation Transient Receptor Potential channel TRPM5 has been shown to correlate with both umami and sweet taste. Also, the phospholipase PLCβ2 was shown to similarly correlate with umami and sweet taste. This suggests that activation of the G-protein pathway and subsequent activation of PLC β2 and the TRPM5 channel in these ...
