Phosphoproteomic Analysis of Gossypol-Induced Apoptosis in Ovarian Cancer Cell Line, HOC1a
Figure 2
MS/MS spectra for identification of protein phosphorylation sites. (a) The MS/MS spectrum of a doubly charged peptide ion at m/z 1015.94 for MH22+ corresponding to the mass of the peptide GDSETDLEALFNAVMNPK from YAP1. (b) The MS/MS spectrum of a doubly charged peptide ion at m/z 946.91 for MH22+ corresponding to the mass of the peptide SAESPTSPVTSETGSTFK from Isoform 1 of A-kinase anchor protein 12. The underlined residues are the phosphorylation sites.
