Study results from Texas A&M University broaden understanding of biochemistry
Published in Proteomics Weekly, September 24th, 2007
Researchers detail in "The Dcr2p phosphatase destabilizes Sic1p in Saccharomyces cerevisiae," new data in biochemistry. According to a study from the United States, "Initiation of cell division is controlled by an irreversible switch. In Saccharomyces cerevisiae degradation of the Sic1p protein, an inhibitor of mitotic cyclin/cyclin-dependent kinase complexes, takes place before initiation of DNA replication, at a point called START."
"Sic1p is phosphorylated by multiple kinases, which can differentially affect the stability of Sic1p. How phosphorylations that stabilize Sic1p are reversed is unknown. Here we show that the Dcr2p phosphatase functionally and...
