Ligand binding and homology modelling of insect odorant‐binding proteins [PDF]

Physiological Entomology, 2014
Abstract This review describes the main characteristics of odorant‐binding proteins ( OBP s) for homology modelling and presents a summary of structure prediction studies on insect OBP s, along with the steps involved and some ...

Ligand binding and partial characterization of sex-specifically expressed lipocalins of submandibular and lacrimal glands of Syrian hamsters

Scientific Reports
Lipocalins are abundantly expressed secretory proteins that perform diverse roles such as ligand-transport, immunomodulation, cell-signaling, chemical communication etc.

A G protein-gated K channel is activated via beta 2-adrenergic receptors and G beta gamma subunits in Xenopus oocytes [PDF]

, 1995
In many tissues, inwardly rectifying K channels are coupled to seven- helix receptors via the Gi/Go family of heterotrimeric G proteins. This activation proceeds at least partially via G beta gamma subunits.

Olfactory decline tracks central‐to‐peripheral spread of tau pathology in Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Abstract INTRODUCTION Olfactory decline often precedes cognitive symptoms in Alzheimer's disease (AD) and is linked to tau pathology. Yet, whether tau aggregates start in peripheral olfactory structures or spread from central regions remains debated. METHODS We analyzed 34 post mortem human olfactory bulb (OB) and 2 neuroepithelium (ONE) samples across

Expression pattern analysis of odorant-binding proteins in the pea aphid Acyrthosiphon pisum [PDF]

, 2015
Odorant-binding proteins (OBPs) are soluble proteins mediating chemoreception in insects. In previous research, we investigated the molecular mechanisms adopted by aphids to detect the alarm pheromone (E)-\u3b2-farnesene and we found that the recognition

Molecular bases of insect odorant receptor function: specificity and evolution

Biological Reviews, Volume 101, Issue 2, Page 1036-1049, April 2026.
ABSTRACT Insect odorant receptors (ORs) are a class of chemoreceptors that insects use to detect volatile cues in their environment. In recent years, major advances in the field of structural biology have made it possible to obtain the first structures of insect ORs.

Expression of pheromone binding proteins during antennal development in the gypsy moth Lymantria dispar [PDF]

, 1989
We have identified 2 olfactory specific proteins in the gypsy moth Lymantria dispar that are uniquely associated with the male antennae, the principal olfactory organs of this animal.

Identification of Genes Involved in Chemoreception in Plutella xyllostella by Antennal Transcriptome Analysis

Scientific Reports, 2017
Perception of environmental and habitat cues is of significance for insect survival and reproduction. Odor detection in insects is mediated by a number of proteins in antennae such as odorant receptors (ORs), ionotropic receptors (IRs), odorant binding ...

Generation of Nano‐Antibodies Targeting the SNMP1 Membrane Receptor of Spodoptera littoralis Using Extracellular Vesicles

Journal of Extracellular Biology, Volume 5, Issue 4, April 2026.
Extracellular vesicles (EVs) represent an excellent platform for the expression of recombinant membrane proteins and their use in llama immunization to generate nano‐antibodies (Nabs). In this study, we present a novel strategy, termed the multi‐layer approach, for EV immobilization in biopanning and ELISA applications.
