Summary
Enables [pyruvate dehydrogenase (acetyl-transferring)]-phosphatase activity. Involved in autophagy of mitochondrion; macroautophagy; and regulation of mitophagy. Located in mitochondrial intermembrane space and mitochondrial matrix. Human ortholog(s) of this gene implicated in maple syrup urine disease. Orthologous to human PPM1K (protein phosphatase, Mg2+/Mn2+ dependent 1K). [provided by Alliance of Genome Resources, Jul 2025]
