Summary of identified phosphosites, phosphopeptides, and phosphoproteins. a 89% of peptides with confidently assigned phosphosites were singly phosphorylated. b Majority of the 1227 confidently assigned phosphosites were pSer. c Overlap between the phosphoproteome and the proteome measured by [7], less than 10% of the proteome is covered by the phosphoproteome dataset representing 125 proteins. Coefficient of correlation between protein and corresponding phosphopeptides identified in c were calculated (Additional file 2: Table S3), in d the coefficient of correlation mean was calculated for each functional category excluding protein with unknown function
