Binding Specificity of Native Odorant-Binding Protein Isoforms Is Driven by Phosphorylation and O-N-Acetylglucosaminylation in the Pig Sus scrofa

Frontiers in Endocrinology, 2019
Odorant-binding proteins (OBP) are secreted in the nasal mucus at the vicinity of olfactory receptors (ORs). They act, at least, as an interface between hydrophobic and volatile odorant molecules and the hydrophilic medium bathing the ORs. They have also

An Olfactory Piriform Cortex‐Lateral Hypothalamus Neural Circuit Contributes to Linalool‐Induced Analgesia

CNS Neuroscience &Therapeutics, Volume 32, Issue 8, August 2026.
Linalool odor exposure activates a glutamatergic projection from the piriform cortex to the lateral hypothalamus (PiriGlu‐LH), mediating descending inhibitory pain pathways. This demonstrates a novel neural mechanism for olfactory‐induced pain modulation and suggests potential therapeutic implications for pain management.

Silencing of Odorant-Binding Protein Gene OBP3 Using RNA Interference Reduced Virus Transmission of Tomato Chlorosis Virus

International Journal of Molecular Sciences, 2019
Tomato chlorosis virus (ToCV) is widespread, seriously impacting tomato production throughout the world. ToCV is semi-persistently transmitted by Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae). Currently, insect olfaction is being studied to develop

Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits

Advanced Science, Volume 13, Issue 39, 13 July 2026.
Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.

Odorant Binding Characteristics of Three Recombinant Odorant Binding Proteins in Microplitis mediator (Hymenoptera: Braconidae)

Journal of Chemical Ecology, 2014
Odorant binding proteins (OBPs) are believed to be important for transporting semiochemicals through the aqueous sensillar lymph to the olfactory receptor cells within the insect antennal sensilla. In this study, three new putative OBP genes, MmedOBP8-10, were identified from a Microplitis mediator (Hymenoptera: Braconidae) antennal cDNA library ...

Odorant-Binding Protein 2 is Involved in the Preference of Sogatella furcifera (Hemiptera: Delphacidae) for Rice Plants Infected with the Southern Rice Black-Streaked Dwarf Virus

Florida Entomologist, 2019
Southern rice black-streaked dwarf virus, transmitted by the white-backed planthopper (Sogatella furcifera [Horvath]) (Hemiptera: Delphacidae) was first found in Guangdong Province, China. A previous study has demonstrated that the host plant preferences

Expressions of Olfactory Proteins in Locust Olfactory Organs and a Palp Odorant Receptor Involved in Plant Aldehydes Detection

Frontiers in Physiology, 2018
The main chemosensory organs of locusts consisted of the antennae and the mouthparts (maxillary and labial palps), which are suggested to perform different functions.

Characterization of odorant binding and chemosensory protein families in the kissing bug Triatoma infestans: comparative analysis among Heteroptera species.

BMC Genomics
Background Plasticity in sensory perception and tolerance to xenobiotics contributes to insects’ adaptive capacity and evolutionary success, by enabling them to cope with potentially toxic molecules from the environment or internal milieu.

A Highly Selective Biosensor Based on Peptide Directly Derived from the HarmOBP7 Aldehyde Binding Site

Sensors, 2019
This paper presents the results of research on determining the optimal length of a peptide chain to effectively bind octanal molecules. Peptides that map the aldehyde binding site in HarmOBP7 were immobilized on piezoelectric transducers.

Odorant-binding protein. Characterization of ligand binding.

Journal of Biological Chemistry, 1990
We have characterized the odorant binding properties of purified bovine odorant-binding protein (OBP) using as a ligand [3H]3,7-dimethyloctan-1-ol ([3H]DMO). A broad variety of odorants, including terpenes, aldehydes, esters, and musks, bind to OBP with affinities of 0.2 to 100 microM.
