Kristine Harjes: The first class that we wanted to talk about, I don't know if we've ever actually mentioned these by names on the show, but we've talked about examples of them in abundance, and these are GPCRs. Max, can you take over from here? What exactly are these? Max Macaluso: Sure. GPCR stands for G-Protein-Coupled Receptor. They're also cal... Read More
