Supplementary Figure S2. Serine-38 of Ana2 is phosphorylated in vitro by Plk4 as identified by mass-spectrometry. Phospho-Mascot-interpreted fragmentation spectra of the peptide 13-LAPRP…EV (phospho-S-38) ILFG…SPR-65 with phosphorylated serine at the position 38 (highlighted red). Labelled peaks correspond to fragment ions. Despite the relatively long peptide, the fragmentation pattern unambiguously identifies the phosphorylation site.
