WebbIf hydrolyzable GTP was used in the assay, the GTP would be hydrolyzed back to GDP by the GTPase activity of the Gα protein (turnover), removing the radiolabeled gamma phosphate from the radiochemical and leaving no radioisotope associated with the cell membrane for detection. Figure 1. GTP binding upon activation of a GPCR. Figure 2. WebbHowever, we were not able to calculate the exact turnover number of rat and mouse COX-1 and COX-2 proteins because the recombinant rat and mouse COXs are not commercially available. To estimate mouse turnover numbers, we used cell lysate prepared from Raw 264.7 cells after LPS stimulation, which is a standard method to selectively induce COX-2.
