An immunoprecipitation method was used to measure [32P]phosphate incorporation into the adenylyl cyclase VI protein in Chinese Hamster Ovary (CHO) cells stably expressing the human δ-opioid receptor. Chronic SNC 80 ((+)-4-[(αR)-α-((2S,5R)-4-allyl-2,5-dimethyl-1-piperazinyl)-3-methoxybenzyl]-N,N-diethyl-benzamide) (1 μM, 24 h) treatment increased the incorporation of [32P] into a 200 kDa protein band 2.5-fold after gel electrophoresis. The increase in phosphorylation of adenylyl cyclase VI was antagonized by naltrindole (1 μM) and the immunoprecipitation was prevented by the saturation of the antibody with the blocking peptide.
