Shifting our perspective on orphan G protein-coupled receptors

Nature Structural & Molecular Biology volume 31, pages 582–583 (2024)Cite this article

Subjects

G protein-coupled receptors (GPCRs) with no known endogenous ligand are termed orphans. Deorphanization of a GPCR involves identifying the ligand, which can be a painstaking exercise. In this Comment, we discuss the challenges in the process, its role in drug discovery and alternative approaches to characterizing orphan GPCRs.
