Phosphopeptide mapping
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. WebDec 19, 1997 · Two-dimensional phosphopeptide mapping experiments indicate that Ser-831 is the major site of CaM kinase II phosphorylation on GluR1. In addition, treatment of hippocampal slice preparations with phorbol esters and forskolin increase the phosphorylation of serine 831 and 845, respectively, indicating that protein kinase C and …
