Phosphorylation of proteins is a predominant reversible post-translational modification. It is central to a wide variety of physiological responses and signaling mechanisms. Recent advances have allowed the global scope of phosphorylation to be addressed by mass spectrometry using phosphoproteomic approaches. In this perspective we discuss four aspects of phosphoproteomics; namely insights and implications from recently published phosphoproteomic studies, and applications and limitations of current phosphoproteomic strategies. As about 50,000 known phosphorylation sites do not yet have any ascribed function, we present our perspectives on a major function of protein phosphorylation that may be of predictive value in hypothesis based investigations. Finally we discuss strategies to measure stoichiometry of phosphorylation in a proteome-wide manner which is not provided by current phosphoproteomic approaches.
