Mutations of signal-transducing G proteins in human disease.

Abstract excerpt

Heterotrimeric guanine nucleotide binding proteins (G proteins) couple a large number of cell surface receptors to their intracellular effector molecules, such as enzymes or ion channels. Mutations of G proteins can lead to either activation or inactivation of the corresponding signal transduction pathway and thus cause clinical symptoms. Mutations of heterotrimeric G proteins have been found in a number of...
