The functional role of protein phosphorylation is impacted by its fractional stoichiometry. Thus, a comprehensive strategy to study phosphorylation dynamics should include an assessment of site stoichiometry. Here we report an integrated method that relies on phosphatase treatment and stable-isotope labeling to determine absolute stoichiometries of protein phosphorylation on a large scale. This approach requires the measurement of only a single ratio relating phosphatase-treated and mock-treated ...[more]
