When it comes to G proteins, cell biologists have amassed a great wealth of material. They have identified nearly 30 of these proteins, which serve as key relays in the pathways that transmit signals from hormones, neurotransmitters, and other cellular regulators from the cell membrane to the interior. And studies with cultured cells have enabled researchers to learn a great deal about the biochemistry of G proteins...
