In the Gbeta5(-/-) mouse, the electroretinogram (ERG) b-wave is absent, and the R7 subfamily of regulators of G protein signaling (RGS), which includes RGS6, -7, -9, and -11, is downregulated. Mutant mouse strains deficient in RGS7 or -11 were characterized, and the SG711 strain which is deficient in both proteins was examined, to learn whether the loss of some of these RGS proteins causes the absence of the ERG b-wave.
