Researchers from Heidelberg University and Sendai University in Japan have used new biotechnological methods to study how human cells react to and further process external signals. They focused on the interaction between so-called G-proteins—the "mediators" of signal transmission—and the receptors known as GPCRs, which trigger signal processes. The researchers not only gained a better understanding of GPCR-G-protein interactions; they are now able to predict their functions better than before.
