![]() | ![]() タイトル: The structure of human sweetness. 著者: Zhang Juen / Zhengyuan Lu / Ruihuan Yu / Andrew N Chang / Brian Wang / Anthony W P Fitzpatrick / Charles S Zuker / ![]() 要旨: In humans, the detection and ultimately the perception of sweetness begin in the oral cavity, where taste receptor cells (TRCs) dedicated to sweet-sensing interact with sugars, artificial sweeteners, ...In humans, the detection and ultimately the perception of sweetness begin in the oral cavity, where taste receptor cells (TRCs) dedicated to sweet-sensing interact with sugars, artificial sweeteners, and other sweet-tasting chemicals. Human sweet TRCs express on their cell surface a sweet receptor that initiates the cascade of signaling events responsible for our strong attraction to sweet stimuli. Here, we describe the cryo-electron microscopy (cryo-EM) structure of the human sweet receptor bound to two of the most widely used artificial sweeteners-sucralose and aspartame. Our results reveal the structural basis for sweet detection, provide insights into how a single receptor mediates all our responses to such a wide range of sweet-tasting compounds, and open up unique possibilities for designing a generation of taste modulators informed by the structure of the human receptor. | ||||||
