We demonstrate that the G protein Gi3 is the cellular target of the adenosine A3 receptor (A3R). By using a cell permeable peptide comprising the C-terminal end of Gαi3 fused to an importation sequence (ALL1) as a selective inhibitor of Gi3 signaling, we show that by coupling to Gi3, the A3R stimu...
