Abstract: New genetic and protein interaction data suggest that G protein α subunits may have partners with primary sequences that are quite divergent. How this is achieved may be through the adoption of similar structures, the β propeller, by both proteins containing WD-40 repeats and kelch domains. Gettemans et al. describe results in yeast that suggest that kelch-domain proteins may serve as previously unrecognized β subunits in the heterotrimeric G protein complex.
