Ppa2 Gene Summary [Mouse]
Enables protein serine/threonine phosphatase activity. Predicted to be involved in diphosphate metabolic process; phosphate-containing compound metabolic process; and regulation of mitochondrial membrane potential. Located in mitochondrion. Is active in synapse. Orthologous to human PPA2 (inorganic pyrophosphatase 2). [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 Ppa2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
