A large body of experimental evidence exists that links heterotrimeric guanosine triphosphate–binding protein (G protein) structure to function. The determination of the crystal structures of G proteins in various activational states and, more recently, in complexes with effectors and other signaling partners highlights the varied mechanisms involved in G protein regulation. Signaling complexes, such as the recently solved complex of Gß *Corresponding author. E-mail: heidi.hamm{at}vanderbilt.edu
