Abstract
This chapter introduces a novel approach to the study of G-protein function in vivo in which transgenic mice are created that harbor α conditional, tissue-specific expression vector that can produce RNA antisense to target mRNA(s). The central role of G proteins in transmembrane signaling from the superfamily of G-protein-linked receptors (GPLRs) to a less populous class of effector molecules that includes adenyl cyclase, phospholipase C (PLC), and various ion channels needs little explanation (see earlier review articles 1–10). Much less obvious is the pivotal role G proteins play in more complex biological processes, such as growth and development. Infectious diseases such as cholera and whooping cough, for example, express elements of their pathology via covalent modification (mono-adenosine diphosphate [ADP]-ribosylation) of G-protein targets. In endocrine tissues, mutations of specific G-protein subunits have been shown to induce tumor growth (11). Finally, genetic mutations of G proteins have been linked to pseudo-hypoparathyroidism, McCune-Albright syndrome (MAS), and Albright’s hereditary osteodystrophy in humans (12).
