Taste receptor type 2 member 4 is a protein that in humans is encoded by the TAS2R4 gene. [5] [6] [7]
This gene encodes a member of a family of candidate taste receptors that are members of the G protein-coupled receptor superfamily and that are specifically expressed by taste receptor cells of the tongue and palate epithelia. These apparently intronless genes encode a 7-transmembrane receptor protein, functioning as a bitter taste receptor. This gene is clustered with another 3 candidate taste receptor genes in chromosome 7 and is genetically linked to loci that influence bitter perception. [7] The geographic distribution of TAS2R4 and TAS2R5 missense allele variants which prevent expression of the receptors is aligned with the distributions of tannin sorghum and the destructive agricultural bird pest in Africa, indicating the role of human taste in developing agroecosystems fitting local environments. [8]
Ligands listed in BitterDB include quinine, parthenolide, denatonium, some non-sugar sweeteners including sucralose and stevioside, and several oligopeptides. [9]
TAS2R16 is a human gene that encodes for a receptor that may play a role in the perception of bitterness.
Taste receptor type 2 member 1 (TAS2R1/T2R1) is a protein that in humans is encoded by the TAS2R1 gene. It belongs to the G protein-coupled receptor (GPCR) family and is related to class A-like GPCRs, they contain 7 transmembrane helix bundles and short N-terminus loop. Furthermore, TAS2R1 is member of the 25 known human bitter taste receptors, which enable the perception of bitter taste in the mouth cavity. Increasing evidence indicates a functional role of TAS2Rs in extra-oral tissues.
Taste receptor type 2 member 3 is a protein that in humans is encoded by the TAS2R3 gene.
Taste receptor type 2 member 8 is a protein that in humans is encoded by the TAS2R8 gene.
Taste receptor type 2 member 9 is a protein that in humans is encoded by the TAS2R9 gene.
Taste receptor type 2 member 10 is a protein that in humans is encoded by the TAS2R10 gene.
Taste receptor type 2 member 13 is a protein that in humans is encoded by the TAS2R13 gene.
Taste receptor type 2 member 5 is a protein that in humans is encoded by the TAS2R5 gene.
Taste receptor type 2 member 7 is a protein that in humans is encoded by the TAS2R7 gene.
Taste receptor type 2 member 39 is a protein that in humans is encoded by the TAS2R39 gene.
Taste receptor type 2 member 40 is a protein that in humans is encoded by the TAS2R40 gene.
Taste receptor type 2 member 41 is a protein that in humans is encoded by the TAS2R41 gene.
Taste receptor type 2 member 43 is a protein that in humans is encoded by the TAS2R43 gene.
Taste receptor type 2 member 45 is a protein that in humans is encoded by the TAS2R45 gene.
Taste receptor type 2 member 46 is a protein that in humans is encoded by the TAS2R46 gene.
Taste receptor type 2 member 30 is a protein that in humans is encoded by the TAS2R30 gene.
Taste receptor type 2 member 19 is a protein that in humans is encoded by the TAS2R19 gene. It seems to be involved in the perception of salt and bitter tastes.
Taste receptor type 2 member 20 is a protein that in humans is encoded by the TAS2R20 gene.
Taste receptor type 2 member 50 is a protein that in humans is encoded by the TAS2R50 gene.
Taste receptor type 2 member 60 is a protein that in humans is encoded by the TAS2R60 gene.
