Concentration-response curves were determined with an immunoprecipitation accumulation assay with increasing concentrations of the analogs. Functional investigations are shown for position 36 of hPP and Phe7.35 of hY4R. COS-7 cells were transiently co-transfected with hY4R constructs and the chimeric G protein GαΔ6qi4myr.
