The Current State and Future of GPCR Drug Development: Empowered by Cryo-EM

G-protein coupled receptors (GPCRs) have long been regarded as one of the most promising and intensively studied drug targets in the pharmaceutical industry. These membrane-bound receptors play crucial roles in a wide range of physiological processes, making them attractive targets for developing therapeutics targeting various diseases, including cancer, cardiovascular disorders, metabolic disorders, and neurological conditions.

The Current Landscape of GPCR Drug Development GPCRs have been at the forefront of drug discovery efforts for decades, and their importance is evident in the fact that approximately 34% of FDA-approved drugs target these receptors. However, despite their immense potential, the development of GPCR-targeted drugs has been hindered by significant challenges, primarily due to the inherent complexity and dynamic nature of these membrane-bound proteins.

Historically, structural elucidation of GPCRs has been a formidable task, as traditional techniques like X-ray crystallography struggled to capture their intricate structures and conformational dynamics. This limitation has posed a significant obstacle in rational drug design and has slowed the progress of GPCR-targeted drug development.

The Cryo-EM Revolution The advent of cryo-electron microscopy (cryo-EM) has ushered in a new era of structural biology, offering unprecedented opportunities for the study of challenging protein targets, including GPCRs. Cryo-EM allows researchers to visualize protein structures at near-atomic resolution without the need for crystallization, overcoming a major hurdle in the structural elucidation of membrane-bound proteins.

Shuimu BioSciences (ShuimuBio), a leading global cryo-EM and AI platform, has been at the forefront of this revolution. By leveraging its cutting-edge cryo-EM facilities and expertise, ShuimuBio has achieved remarkable breakthroughs in GPCR structural determination, including the pioneering resolution of the GPR75 receptor structure – a key target for anti-obesity therapeutics.
