GPCRs Special Issue

Like Comment

In this Special Issue, The FEBS Journal highlights the important roles of G protein-coupled receptors (GPCRs) in cell physiology through fourteen Review Articles, a Viewpoint and a Structural Snapshot. GPCRs comprise the most abundant group of human cell surface receptors and perform key roles in diverse physiological processes. They have, therefore, emerged as attractive drug targets in human disease. Given the direct link between a protein’s structure and its function, the structural characterisation of GPCRs is considered of immense significance to shed light on their functional roles in the signalling pathways in which they are involved. In this editorial, Guest Editor of the Special Issue Arun Shukla reviews the latest advances in the field of activation, regulation and signalling of GPCRs as presented in this special series of articles, and we encourage you to refer to the editorial for an overview of the issue.

The articles included in this Issue emphasise how broadening our knowledge of the structure of GPCRs has aided the understanding of their activation and downstream signalling, which in turn supports the development of drugs targeting GPCRs in a specific and efficient manner.

We hope that experts and newcomers to the field alike will find these reviews timely and interesting. Many thanks go to all the authors for their remarkable contributions to this Special Issue on GPCRs.
