Figure 4. Post-transcriptional control of RAC and proteasome subunit abundance by Mpk1.

a, Relative abundance of the indicated proteins in cells treated with rapamycin (Rapa) for 4 hours relative to untreated cells. b, Relative abundance of the indicated mRNA in cells treated with Rapa for 2 hours relative to untreated cells. rpl18a is used as a control. a and b, Data are means ± SD; n=3 biological replicates. *P≤0.05, **P≤0.01; n.s., not significant (two-way ANOVA).
