Functional modulation of PTH1R activation and signaling by RAMP2 (2022)
Journal Article

Receptor-activity-modifying proteins (RAMPs) are ubiquitously expressed membrane proteins that associate with different G protein-coupled receptors (GPCRs), including the parathyroid hormone 1 receptor (PTH1R), a class B GPCR and an important modulat...

Receptor-associated independent cAMP nanodomains mediate spatiotemporal specificity of GPCR signaling (2022)
Journal Article

G protein-coupled receptors (GPCRs) relay extracellular stimuli into specific cellular functions. Cells express many different GPCRs, but all these GPCRs signal to only a few second messengers such as cAMP. It is largely unknown how cells distinguish...

In Vivo cAMP Dynamics in Drosophila Larval Neurons (2022)
Book Chapter

Cyclic adenosine monophosphate (cAMP) is a universal second messenger that mediates a myriad of cell functions across all kingdoms of life. The ability to monitor intracellular changes of cAMP concentration in living cells using FRET-based biosensors... Read More about In Vivo cAMP Dynamics in Drosophila Larval Neurons.

Optical Mapping of cAMP Signaling at the Nanometer Scale (2020)
Journal Article

Cells relay a plethora of extracellular signals to specific cellular responses by using only a few second messengers, such as cAMP. To explain signaling specificity, cAMP-degrading phosphodiesterases (PDEs) have been suggested to confine cAMP to dist... Read More about Optical Mapping of cAMP Signaling at the Nanometer Scale.

A universal bioluminescence resonance energy transfer sensor design enables high-sensitivity screening of GPCR activation dynamics (2018)
Journal Article

G-protein-coupled receptors (GPCRs) represent one of the most important classes of drug targets. The discovery of new GCPR therapeutics would greatly benefit from the development of a generalizable high-throughput assay to directly monitor their acti...

Mechano-dependent signaling by Latrophilin/CIRL quenches cAMP in proprioceptive neurons (2017)
Journal Article

Adhesion-type G protein-coupled receptors (aGPCRs), a large molecule family with over 30 members in humans, operate in organ development, brain function and govern immunological responses. Correspondingly, this receptor family is linked to a multitud... Read More about Mechano-dependent signaling by Latrophilin/CIRL quenches cAMP in proprioceptive neurons.

Experimental and mathematical analysis of cAMP nanodomains (2017)
Journal Article

In their role as second messengers, cyclic nucleotides such as cAMP have a variety of intracellular effects. These complex tasks demand a highly organized orchestration of spatially and temporally confined cAMP action which should be best achieved by...

cAMP Signals in Drosophila Motor Neurons Are Confined to Single Synaptic Boutons (2016)
Journal Article

The second messenger cyclic AMP (cAMP) plays an important role in synaptic plasticity. Although there is evidence for local control of synaptic transmission and plasticity, it is less clear whether a similar spatial confinement of cAMP signaling exis...

“Store-operated” cAMP signaling contributes to Ca2+-activated Cl− secretion in T84 colonic cells (2015)
Journal Article

Model Organisms in G Protein–Coupled Receptor Research (2015)
Journal Article

The study of G protein–coupled receptors (GPCRs) has benefited greatly from experimental approaches that interrogate their functions in controlled, artificial environments. Working in vitro, GPCR receptorologists discovered the basic biologic mechani... Read More about Model Organisms in G Protein–Coupled Receptor Research.

cAMP signaling microdomains and their observation by optical methods (2014)
Journal Article

Real-Time Monitoring of GPCR/cAMP Signalling by FRET and Single-Molecule Microscopy (2014)
Journal Article

G-protein-coupled receptors (GPCRs), located on the surface of virtually every cell in our organism, mediate the effects of many hormones and neurotransmitters. Although GPCRs have been extensively studied for more than 4 decades using pharmacologica... Read More about Real-Time Monitoring of GPCR/cAMP Signalling by FRET and Single-Molecule Microscopy.

Kinetics and mechanism of G protein-coupled receptor activation (2013)
Journal Article

The activation of a G protein-coupled receptor is generally triggered by binding of an agonist to the receptor's binding pocket, or, in the case of rhodopsin, by light-induced changes of the pre-bound retinal. This is followed by a series of a confor... Read More about Kinetics and mechanism of G protein-coupled receptor activation.

Termination and activation of store-operated cyclic AMP production (2012)
Journal Article

Diverse pathophysiological processes (e.g. obesity, lifespan determination, addiction and male fertility) have been linked to the expression of specific isoforms of the adenylyl cyclases (AC1‐AC10), the enzymes that generate cyclic AMP (cAMP). Our la... Read More about Termination and activation of store-operated cyclic AMP production.

Pseudomonas aeruginosaHomoserine Lactone Activates Store-operated cAMP and Cystic Fibrosis Transmembrane Regulator-dependent Cl?Secretion by Human Airway Epithelia (2010)
Journal Article

The ubiquitous bacterium Pseudomonas aeruginosa frequently causes hospital-acquired infections. P. aeruginosa also infects the lungs of cystic fibrosis (CF) patients and secretes N-(3-oxo-dodecanoyl)-S-homoserine lactone (3O-C12) to regulate bacteria...

Store-operated cyclic AMP signalling mediated by STIM1 (2009)
Journal Article

Depletion of Ca2+ from the endoplasmic reticulum (ER) results in activation of plasma membrane Ca2+ entry channels. This 'store-operated' process requires translocation of a transmembrane ER Ca2+ sensor protein, stromal interaction molecule 1 (STIM1)...
