A landmark Cell paper delivers the answer—mapping how conserved and variable sequence–structure elements govern interaction logic across 46 chemokines and 23 GPCRs. The result: a framework for designing ligands with altered receptor preferences. ♦️ Defines “public” vs. “private” binding determinants ♦️ Highlights role of structured + unstructured regions ♦️ Includes a web tool + viral chemokine engineering demo This is a must-read for GPCR modelers, immunopharmacologists, and ligand engineers. ➡️ Read the paper: https://www.cell.com/cell/fulltext/S0092-8674(25)00398-8 #DrGPCR #GPCR #Chemokines #StructuralBiology #Pharmacology #ProteinEngineering #Immunology #DrugDiscovery Previous Next Recent Articles

This new Nature Chemical Biology paper reveals cryo-EM structures of Gq-bound PTH1R—highlighting how N-linked glycans and ICL2 interactions stabilize receptor conformations that favor Gq coupling. ♦️ Two distinct Gq-bound conformations ♦️ Comparison with Gs-bound PTH1R ♦️ Strategic implications for biased agonist design A critical advance for anyone working on class B1 GPCRs, bone biology, or biased signaling. ➡️ Read the paper: https://www.nature.com/articles/s41589-025-01957-6?utm_content=buffer3b1fa&utm_medium=social&utm_source=twitter.com&utm_campaign=buffer #DrGPCR #GPCR #PTH1R #BiasedAgonism #CryoEM #Pharmacology #Osteoporosis #DrugDiscovery Previous Next Recent Articles

Full Agenda Adhesion GPCR workshop 2024 CINVESTAV, Mexico City, Mexico October 23-25 Download PDF Program HERE < Back to Full Agenda Session IX / Technology capsule: Light on aGPCR signaling and function NovoiSMART - A new platform for GPCR antibody drug discovery Abstract Developing monoclonal antibody drugs against GPCRs and other multi-pass transmembrane targets, such as ion channels, remains a significant challenge. Novoprotein developed a NovoiSMART technology, utilizing mRNA-based immunization, which can overcome these obstacles by producing high-quality antibodies that more accurately mimic natural protein structures. This approach contrasts with other antigen forms like peptides or DNA, which face limitations in structural integrity and immunogenicity. mRNA technology, demonstrated in the success of COVID-19 vaccines, is emerging as a promising method for antibody discovery. Several case studies of GPCR and other multi-pass transmembrane targets are presented, including GPRC5D, Claudin 6 and Napi2b. These studies show that mRNA immunization yields higher antibody titers and greater epitope diversity compared to other methods. These examples underscore the potential of NovoiSMART technology in developing highly specific antibodies for complex targets, with implications for overcoming challenges like drug resistance and tumor escape. About Gavin Zhang Gavin is a currently a director of business and operations at Novoprotein Scientific. His research experience includes phylogenetics and cancer epigenetics.
