Comment on "Oscillations in NF-κB Signaling Control the Dynamics of Gene Expression"

Fusing fluorescent moieties to signaling proteins of interest has allowed for the imaging of subcellular events in live cells in the hope of revealing the dynamic behavior of signal transduction networks ([ 1 ][1]–[ 5 ][2]). Nelson et al . ([ 5 ][2]) recently described a tour de force experimental
