FIG. 4.
Validation of selected candidate phosphopeptides by PRM assays. (A) Workflow of the validation approach that was carried out by using PRM assays for a subset of altered phosphosites. (B) MAPT. (C) MARCKS. The peptide sequences and p-values are shown in each case. MARCKS, myristoylated alanine-rich protein kinase C substrate; PRM, parallel reaction monitoring.
