Results were recorded after 3-5 days of yeast growth on minimal media containing 1 mM methionine to identify proteins that interact specifically with GPA1 as indicated by the extent of yeast growth. (+) indicates moderate growth while (++) indicate heavy yeast growth. Empty vector control plates did not show growth (data not shown). X-Cub-PLV, candidate GPCR-Cub-PLV fusions. Nubwt, wild type amino-terminal half of ubiquitin. NubG, reduced affinity mutant of Nubwt.
