Chemistry.And this year's Nobel Prize in Chemistry The Nobel Prize in Chemistry (Swedish: Nobelpriset i kemi) is awarded once a year by the Royal Swedish Academy of Sciences. It is one of the six Nobel Prizes. The first prize was awarded in 1901. goes to three scientists for their discovery in the early 1980s of how cells mark proteins for destruction. The key turned out to be the molecular tag called ubiquitin u·biq·ui·tin n. A polypeptide found in all eukaryotic cells, including plant cells, that participates in a variety of cellular functions including protein degradation. . Doomed proteins get the label and then are shuttled off to a cell's disposal apparatus, called a proteasome Proteasomes are large protein complexes inside all eukaryotes and archaea, as well as in some bacteria. In eukaryotes, they are located in the nucleus and the cytoplasm.[1] , which slices the proteins into pieces. This selective destruction of unwanted proteins is involved in a number of diseases, including cervical cancer and cystic fibrosis. Aaron Ciechanover and Avram Hershko of the Technion-Israel Institute of Technology in Haifa and Irwin Rose of the University of California The University of California has a combined student body of more than 191,000 students, over 1,340,000 living alumni, and a combined systemwide and campus endowment of just over $7.3 billion (8th largest in the United States). , Irvine will share the prize, which was announced at press time. More on their research will appear in next week's Science News. |
