Phosphopeptide mapping
WebMar 19, 1999 · Comparative phosphopeptide mapping was carried out to characterize the phosphorylation status of inactive and active γ-PAK and to allow the identification of those phosphopeptides whose presence is indicative of γ-PAK activation. WebApr 8, 2004 · Phosphopeptide mapping of wt Flag-eIF4B yielded a pattern identical to the endogenous eIF4B protein ( Figure 4C ). Mutation of Ser406 to Asp (not shown) or Ala ( Figure 4D) had no effect on the phosphopeptide pattern. However, mutation of Ser422 to Ala or Asp (not shown) eliminated phosphopeptide 2.
