Internalization dissociates β2-adrenergic receptors. [PDF]

PLoS ONE, 2011
G protein-coupled receptors (GPCRs) self-associate as dimers or higher-order oligomers in living cells. The stability of associated GPCRs has not been extensively studied, but it is generally thought that these receptors move between the plasma membrane ...

Recent Advances in Photocatalyst‐Driven Protein Labeling and Proximity Mapping

The Chemical Record, EarlyView.
Photocatalyst‐driven protein labeling and proximity mapping have rapidly advanced as powerful strategies for spatiotemporal control in complex biological environments. This review integrates recent developments across single‐electron transfer and energy transfer‐based mechanisms and highlights how catalyst design, reactive intermediates, and diffusion ...

Novel BRET combination for detection of rapamycin-induced protein dimerization using luciferase from fungus Neonothopanus nambi

Heliyon
Bioluminescence resonance energy transfer (BRET) is one of the most promising approaches used for noninvasive imaging of protein-protein interactions in vivo. Recently, our team has discovered a genetically encodable bioluminescent system from the fungus

Detection of the Vascular Endothelial Growth Factor with a Novel Bioluminescence Resonance Energy Transfer Pair Using a Two-Component System

Sensors, 2017
In this paper we describe a two-component BRET (bioluminescence resonance energy transfer)-based method to detect vascular endothelial growth factor (VEGF) molecules in unknown samples as the basis for subsequent in vivo use.

Activation of peripheral NOP receptors reduces periorbital mechanical allodynia evoked by CGRP in mice

British Journal of Pharmacology, EarlyView.
Background and Purpose Migraine is a neurovascular disorder largely mediated by calcitonin gene‐related peptide (CGRP). This study explores the role of the nociceptin/orphanin FQ (N/OFQ)–N/OFQ receptor (NOP) system in CGRP‐induced periorbital mechanical allodynia (PMA) in mice.

An enhanced molecular tension sensor based on bioluminescence resonance energy transfer (BRET) [PDF]

, 2019
ABSTRACT Molecular tension sensors measure piconewton forces experienced by individual proteins in the context of the cellular microenvironment. Current genetically-encoded tension sensors use FRET to report on extension of an elastic peptide encoded in a cellular protein of interest. Here we present the development and characterization

The potential for biased signalling in the P2Y receptor family of GPCRs

British Journal of Pharmacology, EarlyView.
The purinergic receptor family is primarily activated by nucleotides, and contains members of both the G protein coupled‐receptor (GPCR) superfamily (P1 and P2Y) and ligand‐gated ion channels (P2X). The P2Y receptors are widely expressed in the human body, and given the ubiquitous nature of nucleotides, purinergic signalling is involved with a plethora

Ratiometric Detection of Zn²⁺ Using DNAzyme-Based Bioluminescence Resonance Energy Transfer Sensors

Chemistry, 2023
While fluorescent sensors have been developed for monitoring metal ions in health and diseases, they are limited by the requirement of an excitation light source that can lead to photobleaching and a high autofluorescence background.

Agonist‐specific conformational dynamics at the β2‐adrenoceptor dictate allosteric modulation of Gαs signalling and bronchodilation

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose β2‐adrenoceptor (β2AR) agonists are the cornerstone of asthma therapy and promote bronchodilation through Gαs signalling in airway smooth muscle (ASM), but their efficacy is limited by β‐arrestin‐mediated β2AR desensitization.
