**Figure EV1 - A map of human conditional phosphoregulation.**
**A** Venn diagram including the total number of phosphorylated residues for which quantifications were collected and the number of sites contained in the curated phosphosite databases: PhosphositePlus, HPRD and PhosphoELM (August 2014).
**B** Total number of quantified serines (S), threonines (T) and tyrosines (Y).
**C** Distribution of sites reported by multiple parallel publications.
**D** Accumulation of sites as publications are randomly aggregated (100 permutations). Red line shows mean and the shadowed area mean +/- 1 standard deviation.
