Volcano plot of the (−log10) p values vs. the log2 protein abundance differences between Gid10 null yeast vs. WT. Red dots indicate significantly different proteins, determined based on p value < 0.01 and at least fourfold change.   Volcano plot of the (−log10) p values vs. the log2 protein abundance differences between Gid4 null yeast vs. WT. Red dots indicate significantly different proteins in the comparison of Gid10 null yeast vs. WT shown in A.
