Guanosine 5'-O-(3-Thiotriphosphate) 77-86 prepronociceptin Cricetulus griseus 41-44 9384238-9 1997 Similar to opioid receptors, nociceptin binding to the ORL1 receptor was altered by Na+, GTPgammaS and dithiothreitol. Guanosine 5'-O-(3-Thiotriphosphate) 89-98 prepronociceptin Cricetulus griseus 29-39
