Summaries for CYP2S1 Gene

Entrez Gene Summary for CYP2S1 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. [provided by RefSeq, Jul 2008]

GeneCards Summary for CYP2S1 Gene

CYP2S1 (Cytochrome P450 Family 2 Subfamily S Member 1) is a Protein Coding gene. Among its related pathways are acetone degradation I (to methylglyoxal) and Metabolism. 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 CYP2A13.
