Structural biology: A moving story of receptors
Thue W. Schwartz1 & Wayne L. Hubbell2
Abstract
Animals sense light and chemical signals through proteins called G-protein-coupled receptors. The crystal structure of one such receptor in complex with a G-protein fragment shows how these receptors are activated.
The cell membranes of animals — everything from mammals to molluscs, insects and flatworms — contain proteins called G-protein-coupled receptors. Also known as 7TM receptors because of their seven transmembrane helices, they are involved in sensing light and a multitude of chemical signals: not only hormones and other transmitter molecules, but also odours, pheromones and flavours1.
