Drosophila olfactory sensory neurons (OSNs) each express two odorant receptors (ORs): a
divergent member of the OR family and the highly conserved, broadly expressed receptor …

Drosophila melanogaster olfactory neurons have long been thought to express only one
chemosensory receptor gene family. There are two main olfactory receptor gene families in …

In vertebrates, individual olfactory neurons are thought to express a single odorant receptor
(Or) gene, but it is not clear that all odor-evoked activity in each neuron is exclusively …

Olfactory receptors (ORs) are seven transmembrane proteins that are responsible for the
transduction of volatiles into neuronal signals. Their low sequence homology means that the …

By analogy to mammals, odorant receptors (ORs) in insects, such as Drosophila
melanogaster, have long been thought to belong to the G-protein coupled receptor (GPCR) …

Odorant receptors (ORs) constitute the molecular basis for the detection of volatile odorous
molecules and the perception of smell. Our understanding of chemical senses has been …

The OR class insect odorant receptors are ligand-gated ion channels comprised of at least
one common subunit (OR83b in Drosophila) and at least one putative odorant-binding …

Olfactory systems confer the recognition and discrimination of a large number of structurally
distinct odor molecules. Recent molecular analysis of odorant receptor (OR) genes and …

Fruit flies are attracted by a diversity of odors that signal the presence of food, potential
mates, or attractive egg-laying sites. Most Drosophila olfactory neurons express two types of …

Olfaction in Drosophila is mediated by a large family of membrane-bound odorant receptor
proteins (Ors). In heterologous cells, we investigated whether the structural features and …
