Mapping Cellular Signals by David Pescovitz

Shokat’s laboratory focuses on kinases, enzymes that transfer energy stored within the cell to other proteins. The kinases act as control switches for many cellular activities, from development to death. However, with more than 500 kinases in every cell, identifying a specific kinase’s functionality and manipulating it without affecting others in the protein family is no easy task.

Shokat hopes that someday, scientists wielding his chemical-genetic tools will build a map of all the kinases in the cell. Pharmacologists could then consult that map to determine the best drug therapy to fight a particular disease.
