CYP2U1 (cytochrome P450, family 2, subfamily U, polypeptide 1) is a protein that in humans is encoded by the CYP2U1 gene
This gene encodes a member of the superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and the hydroxylation of fatty acids and fatty acid metabolites. CYP2U1 metabolized arachidonic acid, docosahexaenoic acid (DHA), and other long chain fatty acids which suggests that CYP2U1 may play a role in brain and immune functions. CYP2U1 also metabolizes propanone, acetone, and 2-oxypropane.
The CYP2U1 gene is a highly conserved gene that is mainly expressed in brain and thymus, but also at lower levels in kidney, lung, and heart.
