Ppm1k Gene Summary [Mouse]
Predicted to enable manganese ion binding activity and protein serine/threonine phosphatase activity. Involved in regulation of mitochondrial membrane permeability involved in apoptotic process. Located in mitochondrial matrix. Is expressed in several structures, including diaphragm; gut; liver; lung; and spleen. Used to study maple syrup urine disease. 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]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Ppm1k often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
