Cells play a precise game of telephone, sending
messages to each other that trigger actions further on. With clear
signaling, the cells achieve their goals. In disease, however, the
signals break up and result in confused messaging and unintended
consequences. To help parse out these signals and how they function
in health—and go awry in disease—scientists tag proteins with
labels they can follow as the proteins interact with the molecular
world around them.
