Cpox Gene Summary [Rat]
Enables coproporphyrinogen oxidase activity and identical protein binding activity. Involved in several processes, including protoporphyrinogen IX biosynthetic process; response to lead ion; and response to methylmercury. Located in mitochondrial inner membrane. Human ortholog(s) of this gene implicated in hereditary coproporphyria and liver disease. Orthologous to human CPOX (coproporphyrinogen oxidase). [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 rat Cpox often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
