Signalling pathways consist of a series of complex macromolecular interactions that are tightly spatially and temporally regulated and allow signal propagation, amplification and modulation that ultimately leads to a cellular response to stimuli. This research topic aims to provide an overview of existing and emerging experimental and theoretical approaches to study protein-protein interactions (PPIs) that would shed light on the intricate architecture of the transmembrane receptor signalling interactome. We welcome submissions (reviews, research articles, methods, perspectives/opinions, etc.) that address, but are not limited to, the following areas of PPI investigation:
- progress in biophysical methods for monitoring PPIs in living cells based on fluorescence/bioluminescence resonance energy transfer (FRET, BRET, and variants thereof),
- receptor monomers vs. receptor homo- and hetero-oligomerization (functional significance, negative cooperativity, dimer asymmetry, plasma membrane localization, interaction with the cytoskeleton),
- experimental approaches for monitoring dynamic/transient interactions among signalling partners within distinct cellular compartments (e.g., NMR, EPR, single molecule FRET, super-resolution microscopy),
- bioinformatics and computational approaches for the prediction of PPIs and the management/mining of large data sets,
- receptor screening challenges (PPIs-based screening platforms for medium/high throughput screening of compounds),
- biosensor development and its application in living subjects or organoid cultures (advancement of personalized medicine),
- experimental challenges and future trends of PPI research in the field of receptor biology.

This collection will be compiled in cooperation with ERNEST COST Action.
