Included are all phosphopeptides that were significantly induced (P= 0.05 except where indicated) in at least two biological experiments. Bold underlined letters indicate phosphorylation sites located with certainty; non-bold underlined residues are potential sites (i.e. one of the two or three sites is correct). The total number of phosphorylation sites is indicated for peptides where one site could not be localized. Complete data for each protein are listed in Supplementary Table S2.

^*Induction significant only at P = 0.1 in one or more experiments.
