Human Gene CYP4F3 (ENST00000221307.13) from GENCODE V44
  Description: Homo sapiens cytochrome P450 family 4 subfamily F member 3 (CYP4F3), transcript variant 1, mRNA. (from RefSeq NM_000896)
RefSeq Summary (NM_000896): This gene, CYP4F3, encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This protein localizes to the endoplasmic reticulum. The enzyme starts the process of inactivating and degrading leukotriene B4, a potent mediator of inflammation. This gene is part of a cluster of cytochrome P450 genes on chromosome 19. Another member of this family, CYP4F8, is approximately 18 kb away. Several transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Apr 2019].

DESCRIPTION: RecName: Full=Leukotriene-B(4) omega-hydroxylase 2; EC=1.14.13.30; AltName: Full=CYPIVF3; AltName: Full=Cytochrome P450 4F3; AltName: Full=Cytochrome P450-LTB-omega; AltName: Full=Leukotriene-B(4) 20-monooxygenase 2;
FUNCTION: Cytochromes P450 are a group of heme-thiolate monooxygenases. This enzyme requires molecular oxygen and NADPH for the omega-hydroxylation of LTB4, a potent chemoattractant for polymorphonuclear leukocytes.
CATALYTIC ACTIVITY: (6Z,8E,10E,14Z)-(5S,12R)-5,12-dihydroxyicosa- 6,8,10,14-tetraenoate + NADPH + O(2) = (6Z,8E,10E,14Z)-(5S,12R)- 5,12,20-trihydroxyicosa-6,8,10,14-tetraenoate + NADP(+) + H(2)O.
COFACTOR: Heme group (By similarity).
ENZYME REGULATION: Inhibited by carbon monoxide (CO).
PATHWAY: Lipid metabolism; leukotriene B4 degradation.
SUBCELLULAR LOCATION: Endoplasmic reticulum membrane; Single-pass membrane protein (By similarity). Microsome membrane; Single-pass membrane protein (By similarity).
TISSUE SPECIFICITY: Expressed in the polymorphonuclear leukocytes as well as leukocytes.
SIMILARITY: Belongs to the cytochrome P450 family.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
