Scientists have developed a new approach for surveying phosphorylation, a process that is regulated by critical cell signaling pathways and regulates several key cellular signaling events.

Kinase mediated phosphorylation is generally recognised as the major regulator of virtually all metabolic activities in eukaryotic cells including proliferation, gene expression, motility, vesicular transport and programmed cell death.

Researchers at Johns Hopkins took advantage of a new technique that reads the makeup of proteins to identify nearly all chemical changes nature makes by adding phosphate to proteins manufactured in human cells.
