Recently,two different chemicals have been matched as ligands with the same G-protein-coupled receptor(GPCR).Double-pairing of OGR 1 family GPCRs with pro-ton and lysolipid raises several questions.First,whether both are the real ligandsfor the GPCRs.Second,whether modulation ofa GPCR by two chemicals could bepossible.Third,one of the chemicals is proton.Proton-sensing not only is a newaction mode of GPCR activation,but also it could be generalized in other GPCRs.In this review,I’d like to summarize the issue and discuss questions with pharma-cological criteria.
