TAS2R38 is a bitter taste receptor; varying genotypes of TAS2R38 influence the ability to taste both 6- n -propylthiouracil (PROP) [5] and phenylthiocarbamide (PTC). [6][7] Though it has often been proposed that varyi...
Nov 14, 2025 · Complete information for TAS2R38 gene (Protein Coding), Taste 2 Receptor Member 38, including: function, proteins, disorders, pathways, orthologs, and expression. GeneCards - The Human Gene Compendium
The TAS2R38 gene is widely responsible for the well-known bimodal response to a family of bitter chemicals which includes 6-n-propylthiouracial (PROP). There are two common haplotypes of this gene, the recessive AVI a...
TAS2R38 belongs to the large TAS2R receptor family. TAS2Rs are expressed on the surface of taste receptor cells and mediate the perception of bitterness through a G protein-coupled second messenger pathway (summary by...
TAS2R38基因是一种G蛋白偶联受体基因，位于第7号染色体上。 它编码的是一种苦味受体，这些受体分布在人类舌头的味蕾上，会对苦味物质敏感。 在摄入含有苦味物质的食物、饮料时，由TAS2R38基因编码的受体会被激活，相应味觉就会产生苦味的感知。
Dec 2, 2019 · Here we evaluated the role of the bitter receptor TAS2R38 in attainment of longevity, since it has been widely associated with individual differences in taste perception, food preferences, diet ...
味觉 2 受体成员 38： 该基因编码一个七次跨膜 G 蛋白偶联受体，该受体控制对芥子油苷的味觉能力，芥子油苷是一种在芸苔属植物中发现的苦味化合物家族。合成化合物苯硫脲 (PTC) 和 6-正丙基硫氧嘧啶 (PROP) 已被确定为该受体的配体，并已用于测试该基因的遗传多样性。尽管已在世界范围内鉴定出 ...
Jul 22, 2025 · TAS2R38 基因之所以能影响这么多方面，是因为味觉在人类进化中扮演了重要角色。 对苦味敏感的人，可能更容易避开有毒的苦味物质，从而在进化中获得优势。
TAS2R38 是一种 苦味 味觉感受器 [1][2]，该感受器可以尝出 苯硫脲 [3] 和 丙硫氧嘧啶 [4] 或者相关物质的苦味。 这一点和大多数苦味感受器有所不同，即该感受器是对某类物质敏感，而大多数感受器则不会表现出强烈的选择性，能对多种物质做出响应 [5]。
Abstract The ability to taste phenylthiocarbamide (PTC) and 6-n-propylthiouracil (PROP) is a polymorphic trait mediated by the TAS2R38 bitter taste receptor gene. It has long been hypothesized that global genetic dive...
