PLoS Computational Biology, 2020 Over the past two decades, substantial amount of work has been conducted to characterize different odorant receptors, neuroanatomy and odorant response properties of the early olfactory system of Drosophila melanogaster. Yet many odorant receptors remain

Sequence comparisons of odorant receptors among tortricid moths reveal different rates of molecular evolution among family members. [PDF]
PLoS ONE, 2012 In insects, odorant receptors detect volatile cues involved in behaviours such as mate recognition, food location and oviposition. We have investigated the evolution of three odorant receptors from five species within the moth genera Ctenopseustis and ...

Insect Odorant Receptors: Channeling Scent [PDF]
Cell, 2008 Odorant detection in insects involves heterodimers between an odorant receptor (OR) and a conserved seven-transmembrane protein called Or83b, but the exact mechanism of OR signal transduction is unclear. Two recent studies in Nature (Sato et al., 2008; Wicher et al., 2008) now reveal that these OR-Or83b heterodimers form odorant-gated ion channels ...

BMC Genomics, 2018 Background The sense of smell is unrivaled in terms of molecular complexity of its input channels. Even zebrafish, a model vertebrate system in many research fields including olfaction, possesses several hundred different olfactory receptor genes ...

Biosensors, 2023 Non-olfactory cells have excellent biosensor potential because they express functional olfactory receptors (ORs) and are non-neuronal cells that are easy to culture.

Odorant Receptor Desensitization in Insects [PDF]
Journal of Experimental Neuroscience, 2017 Insects and other arthropods transmit devastating human diseases, and these vectors use chemical senses to target humans. Understanding how these animals detect, respond, and adapt to volatile odorants may lead to novel ways to disrupt host localization or mate recognition in these pests. The past decade has led to remarkable progress in understanding

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.
