... channels with a common Orco subunit, unlike the G-protein-coupled olfactory receptors found in vertebrates. Remarkable progress has recently been made in understanding the evolution, development and function of insect odorant receptor neurons (ORNs). These studies have uncovered the diversity of olfactory...

... monophosphate, Fruit fly Odorant receptor Orco Or22a Epac1-camps Chemical stimuli play a central role in insect ecology. Faint concentrations of odorant blends or even single compounds can inform insects, like the fruit fly Drosophila melanogaster , about the presence of, for example, food sources...
