Functional interactions in signaling occur between dopamine D(2) (D(2)R) and cannabinoid CB(1) (CB(1)R) receptors, between CB(1)R and adenosine A(2)A (A(2)AR) receptors, and between D(2)R and A(2)AR. Furthermore, direct molecular interactions have been reported for the pairs CB(1)R-D(2)R, A(2)AR- D(2)R, and CB(1)R-A(2)AR. Here a combination of bimolecular fluorescence complementation and bioluminescence energy transfer techniques was used to identify the occurrence of D(2)R-CB(1)R-A(2)AR hetero-oligomers in living cells.
