Data on preparation and characterization of an insect odorant receptor based biosensor
Data in Brief, 2018 Insect Odorant receptors (OrXs) can be used as the recognition element in a biosensor as they demonstrate high levels of sensitivity and selectivity towards volatile organic compounds.

Identification of new agonists and antagonists of the insect odorant receptor co-receptor subunit. [PDF]
PLoS ONE, 2012 Insects detect attractive and aversive chemicals using several families of chemosensory receptors, including the OR family of olfactory receptors, making these receptors appealing targets for the control of insects.

Odorant Receptor 7D4 Activation Dynamics [PDF]
Angewandte Chemie, 2018 AbstractDeciphering how an odorant activates an odorant receptor (OR) and how changes in specific OR residues affect its responsiveness are central to understanding our sense of smell. A joint approach combining site‐directed mutagenesis and functional assays with computational modeling has been used to explore the signaling mechanics of OR7D4. In this

Bio-benchmarking of electronic nose sensors. [PDF]
PLoS ONE, 2009 BACKGROUND:Electronic noses, E-Noses, are instruments designed to reproduce the performance of animal noses or antennae but generally they cannot match the discriminating power of the biological original and have, therefore, been of limited utility.

Identification of chemosensory genes from the antennal transcriptome of Indian meal moth Plodia interpunctella. [PDF]
PLoS ONE, 2018 Olfaction plays an indispensable role in mediating insect behavior, such as locating host plants, mating partners, and avoidance of toxins and predators. Olfactory-related proteins are required for olfactory perception of insects.

Olfactory receptor antagonism between odorants [PDF]
The EMBO Journal, 2003 The detection of thousands of volatile odorants is mediated by several hundreds of different G protein-coupled olfactory receptors (ORs). The main strategy in encoding odorant identities is a combinatorial receptor code scheme in that different odorants are recognized by different sets of ORs.

Combinatorial Receptor Codes for Odors [PDF]
Cell, 1999 The discriminatory capacity of the mammalian olfactory system is such that thousands of volatile chemicals are perceived as having distinct odors. Here we used a combination of calcium imaging and single-cell RT-PCR to identify odorant receptors (ORs) for odorants with related structures but varied odors.

Heteromeric Anopheline odorant receptors exhibit distinct channel properties. [PDF]
PLoS ONE, 2011 BackgroundInsect odorant receptors (ORs) function as odorant-gated ion channels consisting of a conventional, odorant-binding OR and the Orco coreceptor.
