title: Strategies for shotgun identification of post-translational modifications by mass spectrometry.
abstract: The global identification of post-translationally modified proteins is a difficult challenge that is currently being addressed by many researchers in the field of mass spectrometry (MS)-based proteomics. The ability to identify thousands of proteins by shotgun-based strategies has made the mere idea of a global analysis of a particular protein modification seem reasonable. There has been much progress in the development of methods that make use of shotgun-based protein identification in the analysis of a wide variety of protein modifications, some of which will be discussed here.
