Comparison of the prenylated proteins identified from multinotch SPS-MS3 and MS2-based approaches. (A) Fold-change correlation plot of the prenylated proteins identified from multinotch versus MS2-level quantitative proteomic analyses. A wider dynamic range was observed employing the multinotch approach. (B) Summary of the number of individual prenylated proteins identified from the two approaches. Protein groups were separated into individual proteins. A similar number of proteins were identified with good overlap. (C) Correlation between the enrichment fold-change and relative native abundances of GGTase-I substrates and Rab proteins identified from MS2-based analysis on COS-7 in the presence of statin. No statistically significant correlation was observed.
