Many proteins integrate and are modulated by multiple phosphorylation events derived from complex signaling cues. Simultaneous detection and quantification of temporal changes in all of a protein's phosphorylation sites could provide not only an immediate assessment of a known biochemical activity but also important insights into molecular signaling mechanisms. Here we show the use of stable isotope-based quantitative MS to globally monitor the kinetics of complex, ordered phosphorylation events on protein players in the canonical mitogen-activated protein kinase signaling pathway. In excellent agreement with activity assays and phosphospecific immunoblotting with the same samples, we quantified epidermal growth factor-induced changes in nine phosphorylation sites in the extracellular signal-regulated kinase (ERK)/p90 ribosomal S6 kinase-signaling cassette. Additionally, we monitored 14 previously uncharacterized and six known phosphorylation events after phorbol ester stimulation in the ERK/p90 ribosomal S6 kinase-signaling targets, the tuberous sclerosis complex (TSC) tumor suppressors TSC1 and TSC2. By using quantitative phosphorylation profiling in conjunction with pharmacological kinase inhibitors we uncovered a ERK-independent, protein kinase C-dependent pathway to TSC2 phosphorylation. These results establish quantitative phosphorylation profiling as a means to simultaneously identify, quantify, and delineate the kinetic changes of ordered phosphorylation events on a given protein and defines parameters for the rapid discovery of important in vivo phosphoregulatory mechanisms."xsd:string |
