This protocol describes the essential steps of mass spectrometry-based analysis of protein samples that can be used to identify post-translational arginylation. We describe special considerations for sample preparation and digestion, mass spectrometry analysis using high precision instruments, database searching for the addition of N-terminal Arg, and multiple steps of automated and manual data validation. Data validation is especially important and involves automated data filtering, manual elimination of mass ambiguities, isotopic peak checking, and analysis of the ion fragmentation patterns of the putative arginylated peptides. Currently this protocol represents the only unambiguous method for identification of posttranslationally arginylated proteins and it can be used for identification of new arginylated proteins. This method gives a definitive answer on the identity of arginylated proteins and peptides in simple and complex protein preparations. It is recommended for studies of arginylation and can be applied to other poorly understood post-translational modifications.
