Communication between the cells in your body are managed by substances called hormones. Each cell has a small receiver known as a receptor, which is able to receive hormones. In the 1980s, Brian Kobilka successfully identified the gene that regulates the formation of the receptor for the hormone adrenaline. He and Robert Lefkowitz also discovered that the receptor was similar to receptors located in the eye that capture light. It was later discovered that there is an entire family of receptors that look and act in similar ways–G-protein-coupled receptors. Approximately half of all medications used today make use of this kind of receptor.
