Abstract

There are 18 mammalian cytochrome P450 ( CYP ) families, which encode 57 genes in the human genome. CYP2 , CYP3 and CYP4 families contain far more genes than the other 15 families; these three families are also the ones that are dramatically larger in rodent genomes. Most (if not all) genes in the CYP1 , CYP2 , CYP3 and CYP4 families encode enzymes involved in eicosanoid metabolism and are inducible by various environmental stimuli (i.e. diet, chemical inducers, drugs, pheromones, etc.), whereas the other 14 gene families often have only a single member, and are rarely if ever inducible or redundant. Although the CYP2 and CYP3 families can be regarded as largely redundant and promiscuous, mutations or other defects in one or more genes of the remaining 16 gene families are primarily the ones responsible for P450-specific diseases—confirming these genes are not superfluous or promiscuous but rather are more directly involved in critical life functions. P450-mediated diseases comprise those caused by: aberrant steroidogenesis; defects in fatty acid, cholesterol and bile acid pathways; vitamin D dysregulation and retinoid (as well as putative eicosanoid) dysregulation during fertilization, implantation, embryogenesis, foetogenesis and neonatal development.

  • Mitochondrial CYPs utilize an electron transport chain containing ferredoxin reductase (FDXR) and ferredoxin proteins.

    “While ER-localized CYPs obtain their electrons from a single P450 oxidoreductase, the mitochondrial CYPs utilize an electron transport chain containing the ferredoxin reductase (FDXR) and ferredoxin proteins (34).”
  • Microsomal P450 enzymes require P450 oxidoreductase (POR) for electron transfer.

    “In the endoplasmic reticulum ('microsomes') NADPH donates electrons to the 82-kDa, 2-flavin protein POR, which then donates them to the microsomal steroidogenic P450 enzymes”

  • The human genome encodes 57 cytochrome P450 enzymes, of which 7 are type 1 and 50 are type 2.

    “There are 2 types of human P450 enzymes, type 1 in the mitochondria and type 2 in the endoplasmic reticulum; the human genome encodes 57 cytochrome P450 enzymes, of which 7 are type 1 and 50 are type 2”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
