Abstract

The elucidation of posttranslational modification of proteins is a prerequisite for understanding the molecular details of living organisms, from bacteria to plants and mammals. Protein phosphorylation plays a key role in cell signaling during cellular development, growth, and differentiation. Protein processing is required for the maturation of proteins and for activation and turnover. The ability to detect and monitor posttranslational modifications and processing of proteins by mass spectrometry and other analytical methods is already providing exciting insights into key regulatory events in cells and organisms, in health, and in disease.
