Abstract:Top Down MS analysis of proteins from human cervical carcinoma cell lines and primary human leukocytes harvested from leukoreduction filters provided identification of 261 protein forms, with ∼12% overlap between the two proteomes. The protein forms were produced by 162 unique genes (∼22% overlap). The above information demonstrates the dynamic expression patterns of proteins in various human cell types. Among the above identifications, 89 proteolysis events, 16 methylation events, 10 phosphorylation sites, 7 acetylations (non-N-terminal), and 9 other modifications were observed. These data indicate the significant post-translational complexity present in the human proteome and validate the application of Top Down in complex proteomes, with the most precise molecular characterization of human proteins demonstrated to date.
