Regulators of G-protein signalling (RGS)-sensitive versus RGS-insensitive Gq (A) The fluorescence resonance energy transfer (FRET) ratio change (yellow fluorescent protein:monomeric Turquoise (YFP:mTq)) upon addition of histamine (100 μmol/l) in HeLa cells expressing Gαq-mTqΔ6, Gβ1 and YFP-Gγ2 (n = 4; error bars depict SE). (B) The FRET ratio change (YFP:mTq) upon addition of histamine (100 μmol/l) in HeLa cells expressing Gαq-mTqΔ6-G188S, Gβ1 and YFP-Gγ2 (n = 8).
