Figure 6. Bwc1 and Bwc2 Physically Interact.
The coding regions of the BWC1 and BWC2 genes were fused adjacent to the AD or BD of S. cerevisiae GAL4. Plasmids were cotransformed into a S. cerevisiae strain in which Gal4 regulates the ADE2, HIS3, and lacZ genes. Growth of strains in the absence of adenine (−ade) or histidine (−his) and increased β-galactosidase activity (β-gal, ± one standard error, Miller units) indicate protein-protein interactions.
