UASt regulatory sequences drive expression of a mutated form of Gαq (amino acid replacement H212A).
GαqH212A.UAS/Scer\GAL4GMR.PF partially rescues Gαq961
Expression of Gα49BH212A.Scer\UAS under the control of Scer\GAL4GMR.PF rescues deactivation kinetics but not electroretinogram amplitude in Gα49B961 flies.
