Ready-to-use ELISA kits are available for the detection of Protein Phosphatase 1M, an alias of the protein, protein phosphatase, Mg2+/Mn2+ dependent 1M. The official gene symbol is PPM1M. The protein, with a mass of 30.4 kDa and length of 270 residues, is reported to be nuclear. It is a member of the PP2C family and may be known by other names, including: PP2Ceta, protein phosphatase 2C isoform eta, protein phosphatase 2C eta-2, protein phosphatase 1M (PP2C domain containing), and protein phosphatase 1M.
