Abstract excerpt
beta-Adrenergic receptor (beta AR) agonists modulate a number of intracellular effectors; for example, they stimulate adenylyl cyclase and Ca2+ channels, inhibit Na+ channels and Mg2+ efflux, and activate Na-H exchange. Regulation of adenylyl cyclase, Ca2+, Na+, and Mg2+ by the beta AR is mediated through receptor coupling to the GTP-binding protein Gs. We have previously determined, however, that beta AR...
