The quest to understand heterotrimeric G protein signaling.

ABSTRACT: Over the past fifteen years, great strides have been made to understand how heterotrimeric G proteins control their downstream targets. However, the mechanism by which heterotrimeric G proteins are activated by their upstream G protein-coupled receptors (GPCRs) remains obscure. Recent structural data support the idea that GPCRs, despite their small size, are sophisticated allosteric machines with multiple signaling outputs.
