PPOX - protoporphyrinogen oxidase Gene
Also Known as VP; PPO; V290M
Species: Homo sapiens
About PPOX
This gene has 27 transcripts (splice variants), 202 orthologues, 7 paralogues and is associated with 2 phenotypes. Ubiquitous expression in bone marrow (RPKM 6.3), skin (RPKM 3.4) and 25 other tissues.
Summary
This gene encodes the penultimate enzyme of heme biosynthesis, which catalyzes the 6-electron oxidation of protoporphyrinogen IX to form protoporphyrin IX. Mutations in this gene cause variegate porphyria, an autosomal dominant disorder of heme metabolism resulting from a deficiency in protoporphyrinogen oxidase, an enzyme located on the inner mitochondrial membrane. Alternatively spliced transcript variants encoding the same protein have been identified. [provided by RefSeq, Jul 2008]
