Resum

We describe a positional proteomics approach to simultaneously analyze N-and C-terminal peptides and used it to screen for human protein substrates of granzyme B and carboxypeptidase A4 in human cell lysates. This approach allowed comprehensive proteome studies, and we report the identification of 965 database-annotated protein C termini, 334 neo-C termini resulting from granzyme B processing and 16 neo-C termini resulting from carboxypeptidase A4 processing. © 2010 Nature America, Inc.
