GLC8 Yeast (Saccharomyces cerevisiae) Recombinant produced in E.coli is a single, glycosylated polypeptide chain containing 265 amino acids (1-229) and having a molecular mass of 30.7 kDa (molecular size on SDS-PAGE will appear higher). The GLC8 is fused to a 35 amino acid His Tag at N-Terminus and purified by standard chromatography techniques.
GLC8 is a regulatory subunit of protein phosphatase 1 (Glc7p). GLC8 plays a role in glycogen metabolism and chromosome segregation, and regulates Glc7p activity throµgh conformational alteration; ortholog of the mammalian protein phosphatase inhibitor 2. Under regular conditions, GLC8 triggers GLC7, but when GLC8 is over epxressed, it inhibits Glc7p function. GLC8 is activated upon phosphoylation by Pho85p complexed with four cyclins (Pcl6p, Pcl7p, Pcl8p, or Pcl10p).
