Three researchers who were instrumental in discovering and developing green florescent protein (GFP), which revolutionized how biologists observe the functioning of living cells, have won the 2008 Nobel Prize for Chemistry. linkurl:Osamu Shimomura,;http://www.conncoll.edu/ccacad/zimmer/GFP-ww/shimomura.html now at the Marine Biological Institute in Woods Hole, MA, linkurl:Martin Chalfie,;http://www.columbia.edu/cu/biology/faculty/chalfie/ a Columbia University cell biologist, and linkurl:Roger Tsien,;http://www.tsienlab.ucsd.edu/ a University of California, San Diego biochemist will share more than $1.4 million (USD) when they officially receive the prize in December. The Nobel committee member who announced Shimomura, Chalfie, and Tsien as this year's chemistry prize winners said that GFP has proven to be a "tiny molecular flashlight" shining light on cellular processes that were long obscured by microscopic darkness. The use of GFP to tag and visualize proteins as they function in cells has become widespread in cell and molecular biology, and the technique has been cited in well over 30,000 scientific papers, according to Jeremy Berg, director of the NIH's National Institute of General Medical Sciences. GFP has been used to track key proteins in cancer, HIV, and other diseases that affect humans. "I was not at all surprised and very pleased" to hear the news of the chemistry prize Berg, told __The Scientist__. Berg said that he had been predicting that GFP's Nobel day would come for the past few years and called the florescent technique "part of the fabric of cell biology." According to Tsien, who answered reporters' questions on the phone to Stockholm from his Southern California home, several researchers, such as linkurl:Douglas Prasher;http://www.conncoll.edu/ccacad/zimmer/GFP-ww/prasher.html and linkurl:Sergey Lukyanov,;http://www.the-scientist.com/blog/display/22976/ contributed to the development of GFP as a biological tool. "The three of us will have to serve as the figure heads," he said. "I am very pleased about it." Shimomura discovered GFP lurking in the body of the bioluminescent jellyfish __Aequorea victoria__ in the early 1960s. Shimomura, who was then a researcher at Princeton University, published his findings in a __Journal of Cellular and Comparative Physiology__ linkurl:paper;http://www.ncbi.nlm.nih.gov/pubmed/13911999?ordinalpos=116&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_DefaultReportPanel.Pubmed_RVDocSum in 1962 that has been cited more than 530 times, according to the Institute for Scientific Information (ISI). Shimomura's discovery was the first in what a Nobel committee spokesperson, speaking after the announcement of the prize, called "three distinct acts" in the rise of GFP as a revolutionary cell biology tool. The next act occurred in the early 1990s, when linkurl:Chalfie;http://www.the-scientist.com/article/display/14055/ expressed GFP in the bacterium __Escheria coli__ and the worm __Caenorhabditis elegans__. Chalfie published his findings in a 1994 __Science__ linkurl:paper,;http://www.ncbi.nlm.nih.gov/pubmed/8303295?ordinalpos=1728&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_DefaultReportPanel.Pubmed_RVDocSum which has been cited more than 2,800 times, according to ISI. The key to Chalfie's work was finding that GFP required neither exogenous substrates nor cofactors to fluoresce, making it an ideal, and non-disruptive tracker of gene expression and protein function in living cells and organisms. Tsien is widely regarded as the scientist who developed GFP into a robust linkurl:toolkit;http://www.the-scientist.com/article/display/15826/ for visualizing proteins. By working to understand the mechanisms behind GFP's florescence, Tsien has developed several related proteins that glow in virtually all the colors of the rainbow. His 2004 __Nature Biotechnology__ linkurl:paper;http://www.the-scientist.com/article/display/24849/ introduced florescent red, yellow, and orange protein tags that can be used to visualize complex molecular interactions occurring within living cells. That paper has been cited more than 450 times, according to ISI. Jemermy Berg was not the only one to predict that Tsien was in line for a Nobel Prize. Last week __The Scientist__ published a linkurl:prediction;http://www.the-scientist.com/blog/display/55063/ from Thomson Scientific that named Tsien as a possible recipient of this year's prize. Tsien, however, did not triumph in a linkurl:reader poll;http://www.ziitrend.com/predict/on/who_will_win_the_2008_nobel_prize_in_chemistry_2008-10-08 generated by __The Scientist__ on the user polling site ZiiTrend. Tsien received 21% of the vote (over Harvard nanochemist Charles Leiber and Carnegie Mellon University chemist Krzysztof Matyjaszewski, who got 18% and 19%, respectively), while the majority of voters chose "None of the above." Shimomura and Chalfie could not immediately be reached for comment.

It is these people, particularly Tsien who have made our cells colorful.
