... sensitivity is due to exposure-dependent increases in the expression of odorant receptor (OR) proteins that are activated by specific odorants experienced during imprinting. To test this hypothesis, we exposed juvenile coho salmon, Oncorhynchus kisutch , to the basic amino acid odorant l -arginine during...

.... Summary: An odorant that activates only one odorant receptor, Or7a, in Drosophila larvae becomes strongly attractive at higher concentrations, by recruiting activation of additional odorant receptors. Odorant receptor Aversion Drosophila Olfaction National Institute of Allergy...

..., which is essential to respond with proper action. The olfactory sensory systems in insects share significant similarities with those of vertebrates, although they also exhibit dramatic differences, such as the molecular nature of the odorant receptors (ORs): insect ORs function as heteromeric ion...

...Fabio Miazzi; Bill S. Hansson; Dieter Wicher ABSTRACT Insect odorant receptors are seven transmembrane domain proteins that form cation channels, whose functional properties such as receptor sensitivity are subject to regulation by intracellular signaling cascades. Here, we used the cAMP...

... PLC inhibitor than neomycin, using the procedure described above for identification of odorant receptor site types. Amino acids, but not the bile salt taurocholic acid (or the adenylate cyclase activator, forskolin), were shown to stimulate transduction pathways linked to ion channels within...
