Regulation and role of messengers such as calcium, cyclic AMP, and nitric oxide.

     The goal of Tsien laboratory is to gain a better understanding of information processing, both inside individual living cells and in networks of neurons. They design, synthesize, and use new molecules that detect or manipulate intracellular biochemical signals. Their most versatile mechanism of transducing biochemical events into fluorescence color changes is a quantum mechanical phenomenon called fluorescence resonance energy transfer (FRET). FRET is a general way to detect when fluorophores get within nanometers, i.e., molecular dimensions, of each other. Nondestructive, quantifiable, and biophysically well-understood, FRET has very high resolution in time and space. The challenge is to engineer molecules in which the distance or orientation between the fluorescent partners is specifically sensitive to the desired biochemical signal or event. Ideally the molecules are genetically encodable, because such molecules can be introduced into many intact organisms and targeted to specific tissues, cells, or subcellular locations.

Tsien has been receiving prizes for his work since as far back as 1968, including the W. Alden Spencer Award in Neurobiology from the University of Columbia (1991) and the Pearse Prize from the Royal Microscopical Society (2000). Since 1998 he has been a member of the National Academy of Sciences of the United States.
