How a Human Smell Receptor Works Is Finally Revealed
Human olfactory receptors belong to an enormous family of proteins known as G-protein-coupled receptors (GPCRs). Situated within cell membranes, these proteins contribute to a vast array of physiological processes by detecting all kinds of stimuli, from light to hormones. Over the past two decades, researchers have determined detailed structures for an ever-expanding number of GPCRs—but […]
