James E. Rothman
Born: 3 November 1950, Haverhill, MA, USA
Affiliation at the time of the award: Yale University, New Haven, CT, USA
Prize motivation: "for their discoveries of machinery regulating vesicle traffic, a major transport system in our cells"
Field: biochemistry, cell physiology
Prize share: 1/3
The cells inside our bodies produce a host of different molecules that are sent to specific sites. During transport, many of these molecules are grouped together in tiny sac-like structures called vesicles. These vesicles help transport substances to different places inside the cell and send molecules from the cell's surface as signals to other cells in the body.
During the 1980s and 1990s, James Rothman showed how vesicles fuse with specific surfaces in the cell so that transports arrive at the correct destination.
