Summary of the phosphosite motif data from the SCX-RPLC-CZE-MS/MS in this work and from the SCX-RPLC-MS/MS in reference [45]. Motif-x (http://motif-x.med.harvard.edu/motif-x.html) was used to extract motifs from the data sets. Motif alignment was performed with WebLogo3 (http://webloqo.threeplusone.com/create.cgi). Motif logo of the phosphoserine (A) and phosphothreonine (C) based on the phosphopeptides exclusively identified in the SCX-RPLC-CZE-MS/MS data. Motif logo of the phosphoserine (B) and phosphothreonine (D) based on the phosphopeptides exclusively identified in the SCX-RPLC-MS/MS data.
