Researchers engineer artificial replicas of G protein-coupled receptors

Researchers engineer artificial replicas of G protein-coupled receptors

How do signals from outside the cell cause a response inside it? Such outside signals could be hormones or neurotransmitters. To notice them, the cell's surface possesses receptors. One of the key classes of such receptors are so-called G protein-coupled receptors, or in short GPCRs.
