Entrez Gene Summary for CYP4A22 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 gene is part of a cluster of cytochrome P450 genes on chromosome 1p33. [provided by RefSeq, Jul 2008]

GeneCards Summary for CYP4A22 Gene

CYP4A22 (Cytochrome P450, Family 4, Subfamily A, Polypeptide 22) is a Protein Coding gene. Among its related pathways are Metabolism and Metabolism. GO annotations related to this gene include electron carrier activity and heme binding. An important paralog of this gene is CYP4F12.

UniProtKB/Swiss-Prot for CYP4A22 Gene

  • Catalyzes the omega- and (omega-1)-hydroxylation of various fatty acids such as laurate and palmitate. Shows no activity towards arachidonic acid and prostaglandin A1. Lacks functional activity in the kidney and does not contribute to renal 20-hydroxyeicosatetraenoic acid (20-HETE) biosynthesis.
