In the GPCR-activated pathway, the signal was found to be amplified at the successive steps of the pathway so that the effector molecules are highly expressed compared to ligands. This amplification effect was more pronounced when the respective genes encoding the particular proteins were associated ...
An important aim in cell biology has been to identify and to observe dynamic interactions between protein molecules, as they execute the reactions of a particular biochemical pathway. Concerning GPCRs, despite elucidating ligand binding and signaling, the knowledge and investigation of conformational chan...
Therefore, membrane protein–lipid interactions regulate the first signaling steps initiated through GPCRs: receptors, G proteins, effectors/second messengers and some third messengers. Obviously, other processes involving the interaction of further messengers with internal membranes may also be regulated by...
Indeed, we found that CNO stimulation of DREADD-β2AR in HEK cells successfully mimicked β2AR signaling and induced cAMP synthesis (Fig. 2e, f), acted on the MAPK pathway by suppressing transcription from an SRE reporter (Fig. 2i), recruited β-arrestin 2 (Fig. 4b), and phosphorylated...
In the past two decades, several approximate methods have been suggested for this estimation, which share three basic steps including (1) counting the numbers of synonymous and nonsynonymous sites in the sequences, (2) counting the numbers of synonymous and nonsynonymous differences between the two...
novel steps and signaling crosstalk mechanisms that potentially regulate mitogenic signaling initiated by this class of receptors in various model systems. GPCR Oligomerization and Heterotrimeric G Proteins In recent years, it has become evident that GPCRs can form ...
In this approach, experimental evaluation is performed upon reconstitution of key pathway components into the transfected HEK293T/17 cells, where individual signaling steps of GPCR signaling are monitored by various reporter-based assays (Figure 1B). Specifically, we determined (1) the basal assembly...

pathway in a cell” or “functionally integrated into an endogenous yeast signaling pathway” or “functionally expressed by a host cell”) refers to the ability of a receptor to bind to modulators and transduce that binding event into a signal using components of a signaling pathway of the ...
