Pnpo Gene Summary [Mouse]
Enables pyridoxamine phosphate oxidase activity. Involved in pyridoxal phosphate metabolic process and pyridoxamine metabolic process. Is active in cytosol. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in pyridoxamine 5'-phosphate oxidase deficiency. Orthologous to human PNPO (pyridoxamine 5'-phosphate oxidase).

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 Pnpo often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
