However, in some individuals, pancreatic beta cells fail to ... by the GPCR family of receptors because, although ~1000 GPCRs have been identified, the function of many of these, and the ligands ...

The authors say this may be because it has a longer half-life than other drugs and is nonselective, which means it can bind to any beta receptors. In the study, hypoglycemia was also more likely ...

Beta-blockers antagonize beta-1 and beta-2 receptors which are the usual targets of the sympathetic nervous system, including epinephrine and norepinephrine. This results in a decreased heart rate ...

In the inactive conformation, the a-subunit of the G protein binds to GDP and is bound to a beta-gamma complex (a). Upon receptor activation by its ligand, there is an exchange of GDP for GTP (b).
