Inhibition of Subsets of G Protein-coupled Receptors by Empty Mutants of G Protein α Subunits in Go, G11, and G16 [PDF]

open access: yes, 2000
We previously reported that the xanthine nucleotide binding Goα mutant, GoαX, inhibited the activation of Gi-coupled receptors. We constructed similar mutations in G11α and G16α and characterized their nucleotide binding and receptor interaction.

An in vivo biosensor for neurotransmitter release and in situ receptor activity. [PDF]

open access: yes, 2010
Tools from molecular biology, combined with in vivo optical imaging techniques, provide new mechanisms for noninvasively observing brain processes. Current approaches primarily probe cell-based variables, such as cytosolic calcium or membrane potential ...

Structures of the M1 and M2 muscarinic acetylcholine receptor/G-protein complexes

open access: yesScience, 2019
Choosing a partner G protein–coupled receptors (GPCRs) bind ligands outside the cell and trigger events inside the cell by selectively binding and activating specific G proteins. The selectivity occurs even among highly related GPCRs.

Novel 3D‐Printed Biophotonic Scaffold Displaying Luminescence under Near‐Infrared Light for Photopharmacological Activation and Biological Signaling Compound Release

open access: yesAdvanced Healthcare Materials, EarlyView.
Despite significant efforts in developing novel biomaterials to regenerate tissue, only a few of them have successfully reached clinical use. It has become clear that the next generation of biomaterials must be multifunctional. Smart biomaterials can respond to environmental or external stimuli, interact in a spatial‐temporal manner, and trigger ...

Multitargeting nature of muscarinic orthosteric agonists and antagonists

open access: yesFrontiers in Physiology, 2022
Muscarinic receptors (mAChRs) are typical members of the G protein-coupled receptor (GPCR) family and exist in five subtypes from M1 to M5. Muscarinic receptor subtypes do not sufficiently differ in affinity to orthosteric antagonists or agonists ...

Molecular properties of muscarinic acetylcholine receptors

open access: yesProceedings of the Japan Academy. Series B, Physical and biological sciences, 2013
Muscarinic acetylcholine receptors, which comprise five subtypes (M1-M5 receptors), are expressed in both the CNS and PNS (particularly the target organs of parasympathetic neurons). M1-M5 receptors are integral membrane proteins with seven transmembrane

Body Biofluids for Minimally‐Invasive Diagnostics: Insights, Challenges, Emerging Technologies, and Clinical Potential

open access: yesAdvanced Healthcare Materials, EarlyView.
Recent advances in diagnostics have accelerated the development of miniaturized wearable technologies for the continuous monitoring of diseases. This paradigm is shifting healthcare away from invasive, centralized blood tests toward decentralized monitoring, using alternative body biofluids.

Functional characterization of three G protein-coupled acetylcholine receptors in parasitic nematode Trichinella spiralis

open access: yesInternational Journal for Parasitology: Drugs and Drug Resistance, 2023
The physiological significance of metabotropic acetylcholine receptors in parasitic nematodes remains largely unexplored. Here, three different Trichinella spiralis G protein-coupled acetylcholine receptors (TsGAR-1, -2, and -3) were identified in the ...
