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.

The Anaphase-Promoting Complex (APC) ubiquitin ligase affects chemosensory behavior in \u3cem\u3eC. elegans\u3c/em\u3e [PDF]
, 2016 The regulation of fundamental aspects of neurobiological function has been linked to the ubiquitin signaling system (USS), which regulates the degradation and activity of proteins and is catalyzed by E1, E2, and E3 enzymes. The Anaphase-Promoting Complex

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.

Specialized odorant receptors in social insects that detect cuticular hydrocarbon cues and candidate pheromones. [PDF]
, 2017 Eusocial insects use cuticular hydrocarbons as components of pheromones that mediate social behaviours, such as caste and nestmate recognition, and regulation of reproduction.

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.

Adaptation of olfactory receptor abundances for efficient coding
, 2019 Olfactory receptor usage is highly heterogeneous, with some receptor types being orders of magnitude more abundant than others. We propose an explanation for this striking fact: the receptor distribution is tuned to maximally represent information about ...

Requirement for Slit-1 and Robo-2 in zonal segregation of olfactory sensory neuron axons in the main olfactory bulb [PDF]
, 2007 The formation of precise stereotypic connections in sensory systems is critical for the ability to detect and process signals from the environment. In the olfactory system, olfactory sensory neurons (OSNs) project axons to spatially defined glomeruli ...

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.
