Excited to share our latest @nature.com: How does naloxone (Narcan) stop an opioid overdose? We determined the first GDP-bound μ-opioid receptor–G protein structures and found naloxone traps a novel "latent” state, preventing GDP release and G protein activation.💊🧪 🧵👇 www.nature.com/articles/s41...
