PP2C epsilon/PPM1L: Lysates

PP2C epsilon, also known as PPM1L, is a 34 kDa (predicted) widely expressed Ser/Thr phosphatase. It consists of a 25 amino acid (aa) extracellular domain, a 17 aa transmembrane segment, and a 318 aa cytoplasmic region (aa 43-360) which contains the phosphatase domain (aa 91-344). Alternate splicing generates additional isoforms of human PP2C epsilon with 179 aa or 127 aa N-terminal truncations or a 166 aa C-terminal truncation. The PP2C epsilon-mediated dephosphorylation of TAK1 and ASK1 is regulated by oxidative stress and inflammatory cytokines. Loss of PP2C epsilon function is associated with the development of metabolic syndrome.
