Pheromone receptors
Vomeronasal receptors are a class of olfactory receptors that putatively function as receptors for pheromones. Pheromones have evolved in all animal phyla, to signal sex and dominance status, and are responsible for stereotypical social and sexual behaviour among members of the same species. In mammals, these chemical signals are believed to be detected primarily by the vomeronasal organ WebFeb 25, 2024 · pheromone, any endogenous chemical secreted in minute amounts by an organism in order to elicit a particular reaction from another organism of the same …

WebPheromones are smells that have evolved functions as signals. How the sense of smell works was a mystery until 1991, when Linda Buck and Richard Axel, then both at Columbia University, published their discovery of the highly variable family of almost 1,000 different olfactory receptors in the nose of the mouse. WebReceptors DmelOr69aB and DmelOr69aA are tuned to the pheromone (Z)-4-undecenal (Z4-11Al) that is released by female flies and induces flight attraction in both sexes. Intriguingly, these PR types are also activated by food odorants ( Lebreton et al., 2024 ).
