G protein-coupled receptors (GPCRs), targeted by many medicines, are increasingly understood through allosteric modulation. This review revisits the Monod-Wyman-Changeux (MWC) model to explain emerging GPCR allostery data.
Area of Science:
- Biochemistry
- Molecular Biology
- Pharmacology
Background:
- G protein-coupled receptors (GPCRs) are the largest receptor family and drug targets.
- Allosteric modulation of GPCRs is a rapidly growing field.
- GPCR regulation involves both orthosteric and allosteric ligands.
Purpose of the Study:
- To review the Monod-Wyman-Changeux (MWC) model in light of new GPCR allostery data.
- To connect contemporary GPCR function views with classic allosteric protein models.
Main Methods:
- Literature review of structural, functional, and operational data on GPCR allostery.
- Revisiting the Monod-Wyman-Changeux (MWC) model.
Main Results:
- Emerging data on GPCR allostery aligns with characteristics of allosteric proteins.
- The MWC model provides a framework for understanding diverse GPCR regulation modes.
Conclusions:
- The MWC model offers valuable insights into complex GPCR allosteric mechanisms.
- Understanding GPCR allostery is crucial for drug discovery and development.

Diversity of Antigen Receptors
Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...

GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
