Purity ~95% (SDS-PAGE). Protein phosphatase 2C (PP2C alpha) is a Mn2+- or Mg2+- dependent protein serine/threonine phosphatase that is essential for regulating cellular stress response in eukaryotes. The protein coding region of PP2C alpha (aa1-382) was cloned into an E. coli expression vector. PP2C alpha was overexpressed in E. coli as a soluble His-tag fusion protein, and it was purified by conventional column chromatographic techniques. Source: Recombinant protein corresponding to aa1-382 from human PP2C alpha, expressed in E. coli.
