Histogram of phosphomotifs, including R-x-x-S/T and S/T-P patterns based on CIs. Frequency distribution of CIs for the phosphomotifs including S/T-P and basic amino acid residues at the N-terminals was calculated (see Additional file 3). Each class of the frequency distribution includes a successive group of ten phosphomotifs ordered by CI (rank of CI). Average CIs in a class are presented as plots in the upper panel. The lower panel shows the number of phosphomotifs including R/K-x-x-S/T, R/K-x-x-x-S/T, or R/K-x-S/T (black) and S/T-P (white) patterns for ranked CI. See also Additional file 3.
