Summaries for CYP4B1 Gene

Entrez Gene Summary for CYP4B1 Gene

  • This gene 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. In rodents, the homologous protein has been shown to metabolize certain carcinogens; however, the specific function of the human protein has not been determined. Multiple transcript variants have been found for this gene. [provided by RefSeq, Jan 2016]

GeneCards Summary for CYP4B1 Gene

CYP4B1 (Cytochrome P450 Family 4 Subfamily B Member 1) is a Protein Coding gene. Among its related pathways are Arachidonic acid metabolism and Phase II conjugation. GO annotations related to this gene include iron ion binding and oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen. An important paralog of this gene is CYP4F8.

UniProtKB/Swiss-Prot for CYP4B1 Gene

  • Cytochromes P450 are a group of heme-thiolate monooxygenases. In liver microsomes, this enzyme is involved in an NADPH-dependent electron transport pathway. It oxidizes a variety of structurally unrelated compounds, including steroids, fatty acids, and xenobiotics.
