CYP4F2

Overview

CYP4F2 is a member of the cytochrome P450 superfamily of enzymes. These enzymes are involved in the metabolism of various substances within the body, including drugs and endogenous compounds. CYP4F2 is specifically known for its role in the hydroxylation of leukotriene B4, a process that is crucial for the regulation of inflammatory responses.

Function

CYP4F2 is primarily expressed in the liver and kidney, where it participates in the metabolism of fatty acids and eicosanoids. One of its key functions is the omega-hydroxylation of leukotriene B4, converting it into 20-hydroxy-leukotriene B4, which is less active and more easily excreted from the body.

Clinical Significance

CYP4F2 has been implicated in the metabolism of vitamin E and arachidonic acid. Variations in the CYP4F2 gene can affect the enzyme's activity, influencing an individual's response to certain medications, such as warfarin, and susceptibility to diseases related to inflammation and oxidative stress.

Genetic Variability

The CYP4F2 gene is located on chromosome 19 and exhibits genetic polymorphisms that can lead to variations in enzyme activity. One well-studied polymorphism is the V433M variant, which has been associated with altered warfarin dose requirements in patients.

Related Enzymes

CYP4F2 is part of the CYP4F subfamily, which includes other enzymes such as CYP4F3 and CYP4F11. These enzymes share similar functions but differ in their tissue distribution and substrate specificity.
