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.PPM1K (Protein Phosphatase, Mg2+/Mn2+ Dependent 1K) is a Protein Coding gene. Diseases associated with PPM1K include Maple Syrup Urine Disease, Mild Variant and Intermediate Maple Syrup Urine Disease. Among its related pathways are Valine, leucine and isoleucine degradation and Viral mRNA Translation. GO annotations related to this gene include protein serine/threonine phosphatase activity. An important paralog of this gene is PPM1E.
