Profiling the dynamics of a human phosphorylome reveals new components in HGF/c-Met signaling.

Protein phosphorylation is a dynamic and reversible event that greatly influences cellular function. Identifying the key regulatory elements that determine cellular phenotypes during development and oncogenesis requires the ability to dynamically monitor proteome-wide events. Here, we report the dev...
