Summary
Enables coproporphyrinogen oxidase activity. A structural constituent of eye lens. Involved in heme A biosynthetic process and heme B biosynthetic process. Acts upstream of or within heme biosynthetic process. Located in membrane and mitochondrion. Is active in mitochondrial intermembrane space. Is expressed in embryo; liver; and yolk sac. Used to study hereditary coproporphyria. Human ortholog(s) of this gene implicated in hereditary coproporphyria and liver disease. Orthologous to human CPOX (coproporphyrinogen oxidase).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
