Phosphopeptides identified by MS in percentage compared with the most intense peak, Ser-435
Only the phosphopeptides that have an intensity higher than 1% of the intensity of the most intense peak are presented here. In the absence of PKA, none of the phosphopeptides identified has an intensity higher than 1% of the most intense peak. The phosphorylated residues are indicated in bold.
