    • The present invention relates to the discovery, identification and characterization of a receptor protein, referred to herein as T1R3, which is expressed in taste receptor cells and associated with the perception of bitter and sweet taste. The invention encompasses transgenic animals and cells that do not express functional T1R3 protein, particularly knock-out animals and cells, and transgenic animals and cells that express a non-native T1R3 protein. Experimental model systems based on these animals and cells can be used to study T1R3-mediated taste transduction and responses of the components of the T1R3 signal transduction pathway to various tastants, furthering our understanding of the molecular biology and biochemistry of taste. Such model systems would also be useful for screening for novel tastants and taste modulators, such as enhancers of desirable flavors, and blockers of undesirable flavors.
    • 本发明涉及受体蛋白的发现,鉴定和鉴定,本文称为T1R3,其在味觉受体细胞中表达并与苦味和甜味的感觉相关。 本发明包括不表达功能性T1R3蛋白,特别是敲除动物和细胞的转基因动物和细胞,以及表达非天然T1R3蛋白的转基因动物和细胞。 基于这些动物和细胞的实验模型系统可用于研究T1R3介导的味觉转导和T1R3信号转导通路的成分对各种滋味的反应,进一步促进了对分子生物学和味觉生物学的认识。 这种模型系统还可用于筛选新颖的滋味剂和味觉调节剂,例如所需香料的增强剂和不期望的香料的阻滞剂。
