Summaries for CYP4X1 Gene

Entrez Gene Summary for CYP4X1 Gene

  • This gene encodes a member of the cytochrome P450 superfamily of enzymes and is located within a cluster of genes belonging to this superfamily on chromosome 1. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. The expression pattern of a similar rat protein suggests that this protein may be involved in neurovascular function in the brain. Alternative splicing results in multiple transcript variants.

GeneCards Summary for CYP4X1 Gene

CYP4X1 (Cytochrome P450 Family 4 Subfamily X Member 1) is a Protein Coding gene. Among its related pathways are acetone degradation I (to methylglyoxal) and nicotine degradation IV. 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 CYP4Z1.
