UniProt Protein Function: | CYP4B1: 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. Belongs to the cytochrome P450 family. 2 isoforms of the human protein are produced by alternative splicing. |
UniProt Protein Details: | Protein type:EC 1.14.14.1; Oxidoreductase Chromosomal Location of Human Ortholog: 1p33 Cellular Component: endoplasmic reticulum membrane Molecular Function:iron ion binding; heme binding; drug binding; fluorene oxygenase activity; oxygen binding Biological Process: fluorene metabolic process; biphenyl metabolic process; xenobiotic metabolic process; exogenous drug catabolic process |
NCBI Summary: | 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. Two transcript variants encoding slightly different isoforms have been found for this gene. [provided by RefSeq, Jul 2008] |
