Researchers at the Indian Institute of Technology Kanpur (IIT-K) have developed a novel antibody-based biosensor that can monitor the activation of G protein-coupled receptors (GPCRs) in live cells. GPCRs are the largest family of receptor proteins in human cells and are targeted by more than one-third of all clinically prescribed medicines.

Led by Prof. Arun K. Shukla, the research team has been investigating GPCR biology for over a decade. GPCRs, because of their central role, are considered some of the most important gateways for developing new drugs and therapies. The new biosensor represents a significant milestone in overcoming the technical challenges of monitoring receptor activation...
