Figure 4. A subset of CHPKs display CDK activity.

Figure 4

S. cerevisiae cdc28-13 strains growing in glucose at the permissive temperature and harboring galactose-inducible expression plasmids for the indicated proteins (Empty Vector, EV; human cyclin-dependent kinase 1, CDK1; CHPKs (1–8)) were transferred to galactose-containing media and shifted to the restrictive temperature for five hours, at which time budded cells (indicative of continued cell cycle progression) were counted by light microscopy. The percentage of budded cells is shown with standard deviation. Asterisks denote statistically significant differences from the empty vector control (* indicates P≤0.05, ** indicates P≤0.01).
