Here we show a novel function of Goalpha as a mediator of opioid receptor-induced extracellular signal-regulated kinase activation in neural cells. The current study found that, in neuroblastoma x glioma NG108-15 hybrid cells, activation of extracellular signal-regulated kinase through delta opioid receptors was mediated by pertussis toxin-sensitive G protein and independent of Gbetagamma subunits, PI3 kinase and receptor internalization. Overexpression of a dominant negative form of Goalpha1, but not Gialpha2, completely blocked delta opioid receptor-induced extracellular signal-regulated kinase activity. Decreasing Goalpha expression by RNA interference greatly reduced delta opioid receptor-induced extracellular signal-regulated kinase activity and extracellular signal-regulated kinase-dependent gene expression, while knocking down Gialpha2 did not. By taking advantage of differences between human and mouse Goalpha gene sequences, we simultaneously knocked down endogenous Goalpha expression and expressed exogenous human Goalpha subunits. We found that both human Goalpha1 and Goalpha2 could mediate delta opioid receptor-induced extracellular signal-regulated kinase activation. This study suggests that one of the functions of Goalpha in the brain is to mediate extracellular signal-regulated kinase activation by G protein-coupled receptors."xsd:string |
