This gene encodes a member of the PPM family of Mn2+/Mg2+-dependent protein phosphatases. The encoded protein, essential for cell survival and development, is targeted to the mitochondria where it plays a key role in regulation of the mitochondrial permeability transition pore. [provided by RefSeq, Sep 2012],catalytic activity:A phosphoprotein + H(2)O = a protein + phosphate.,caution:Ref.9 has crystallized PPM1K in the presence of magnesium ions. However, PubMed:17336929 reported that no activity toward p-nitrophenylphosphate was seen in the absence of manganese ions and magnesium could not subsitute for manganese.,cofactor:Binds 1 magnesium or manganese ion per subunit.,function:Regulates the mitochondrial permeability transition pore and is essential for cellular survival and development.,similarity:Belongs to the PP2C family.,similarity:Contains 1 PP2C-like domain.,
