G protein beta interacts with the glucocorticoid receptor and suppresses its transcriptional activity in the nucleus.

Extracellular stimuli that activate cell surface receptors modulate glucocorticoid actions via as yet unclear mechanisms. Here, we report that the guanine nucleotide-binding protein (G protein)-coupled receptor-activated WD-repeat Gbeta interacts with the glucocorticoid receptor (GR), comigrates with it into the nucleus and suppresses GR-induced transactivation of the glucocorticoid-responsive genes. Association of Ggamma with Gbeta is necessary for this action of Gbeta. ... [more]
