The 1994 Nobel Prize
In 1994, the Nobel Prize in Medicine was awarded jointly to Rodbell and Alfred G. Gilman of the University of Texas Southwestern Medical Center for the discovery of G-proteins and their role in signal transduction in cells. Gilman provided a critical piece of the puzzle. He isolated the transducer molecules and defined their structure. Because they were proteins that bind GTP, Gilman called them G-proteins.
"Humans must understand how important it is to think, to seek out [knowledge] and understand what nature is doing"
