VARIETY OF RECEPTORS. “In mammals, which type of chemosensory receptors/olfactory sensory neuron has been coopted to detect the pheromone depends on the molecule: volatile pheromones may be detected by chemosensory neurons in either the main olfactory system or accessory olfactory system. Protein pheromones such as ESP1, ESP22, and darcin are likely detected exclusively by VR2 receptors of the vomeronasal system whereas sulphated steroid pheromones are detected by VR1 receptors. Important amines are detected by trace amine-associated receptors (TAARs).”
