The porcine odorant-binding protein as molecular probe for benzene detection. [PDF]

PLoS ONE, 2018
In recent years, air pollution has been a subject of great scientific and public interests for the strong impact on human health. Air pollution is due to the presence in the atmosphere of polluting substances, such as carbon monoxide, sulfur and nitrogen

Folding, misfolding, and regulation of intracellular traffic of G protein‐coupled receptors involved in the hypothalamic–pituitary–gonadal axis

Andrology, Volume 14, Issue 4, Page 978-991, May 2026.
Abstract Background G protein‐coupled receptors are a large and functionally diverse family of membrane receptors involved in a number of biological processes. Like other proteins, G protein‐coupled receptors need to be properly folded in order to traffic to the plasma membrane and interact with agonist.

Ca2+-sensors and ROS-GC: interlocked sensory transduction elements: a review [PDF]

, 2012
From its initial discovery that ROS-GC membrane guanylate cyclase is a mono-modal Ca2+-transduction system linked exclusively with the phototransduction machinery to the successive finding that it embodies a remarkable bimodal Ca2+signaling device, its ...

Diversity of Odorant-binding Proteins and Chemosensory Proteins in Insects [PDF]

Chemical Senses, 2005
Odour and pheromone perception occurs through a complex series of events, many aspects of which have been elucidated in the most recent years. The discovery of membrane-bound olfactory receptors, both in vertebrates and in insects, and their functional expression in heterologous systems have shown that they can be directly activated by odorant and ...

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

Selectivity of odorant-binding proteins from the southern house mosquito tested against physiologically relevant ligands [PDF]

, 2015
As opposed to humans, insects rely heavily on an acute olfactory system for survival and reproduction. Two major types of olfactory proteins, namely, odorant-binding proteins (OBPs) and odorant receptors (ORs), may contribute to the selectivity and ...

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.

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.

Humidity response depends on the small soluble protein Obp59a in Drosophila

eLife, 2018
Hygrosensation is an essential sensory modality that is used to find sources of moisture. Hygroreception allows animals to avoid desiccation, an existential threat that is increasing with climate change.
