Results – Effect of Pertussis-toxin treatment:

In order to elucidate the identity of the endogenous G subunits mediating the NOP/G₁ interaction, and to evaluate their potential effects on NOP mediated -arrestin 2 recruitment, HEK293 cells stably expressing the human NOP (NOP/RLuc) receptor and either the G₁ subunit (G₁/RGFP) or the -arrestin 2 (-arrestin 2/RGFP) were treated for 20 h with 10 ng PTX. As shown in Fig 2, right panel, PTX treatment abolished the ability of the agonist to stimulate NOP/G-protein interaction, but had negligible effects on the stimulation of NOP/-arrestin 2 interactions…
