The functionality of proteins is dependent on their spatial and temporal distributions, neither of which is directly measured by static protein abundance. Here we report a mass spectrometry-based proteomics workflow and data analysis pipeline, named Simultaneous Proteome Localization and Turnover (SPLAT), to concurrently examine the turnover dynamics and subcellular distributions of whole cell proteomes under perturbation. SPLAT builds on prior work in protein turnover measurements and subcellular localization profiling, by combining dynamic stable isotope labeling, differential ultracentrifugation, and kinetic modeling to concurrently measure changes in protein turnover and subcellular localization under perturbation in one experiment.
