Human Cytochrome P450s

  • Note on Nov. 12, 2013 I have revised pseudogene nomenclature to fit with HGNC requirements. Old nomenclature is retained as synonyms. This is part of an effort to translate the P450 nomenclature to Ensembl, including all pseudogenes.
  • Note on July 22, 2011 I have completed a total revision of this page. All links are now working and new links have been added
  • Note on Jan. 24, 2007 I have completed a total revision of this page.
  • On May 17, I added links to the Human Gene Nomenclature Committee names (HGNC).
  • On Aug. 14, 2009 these links were revised to accommodate a server address change at HGNC.
  • Last revised August 14, 2009 (added CYP19 structure link)
  • I have tried to make this table as up to date as possible. Entrez Gene, OMIM, Unigene and all other links have been checked and updated.
  • I have included seven gene cluster maps that show human, mouse and rat compared (red links in the first column).
  • These maps are further described in: Comparison of cytochrome P450 (CYP) genes from the mouse and human genomes Pharmacogenetics 14, 1-18 2004
  • The Entrez Gene site has extensive data and links for intact sequences and some pseudogenes.
  • For a complete set of human P450 sequences including pseudogenes go to the FASTA file
  • All human P450 genes and all P450 pseudogenes are included in this table.
  • This table contains more than 700 links to human P450 data, including known crystal structures.
  • CYP names in column 1 are linked to their protein sequences, including the pseudogenes.
  • X at the end of a CYP name means that name has been discontinued and replaced by a new name.
  • Pseudogenes are named using suffixes to specify the four types of pseudogenes defined as:
  • P is a full length or near full length pseudogene, it may be near or far from other P450s.
-ps is equivalent to P, but it is required nomenclature for mouse full length pseudogenes.
-de stands for detritus exons (found near other full length genes).
-se stands for solo exons, one or a few exons found distant from a P450 gene.
-ie stands for internal exons, duplicate exons found inside some P450 genes.
