**Background of CYP4F2 Recombinant Protein**
CYP4F2. a member of the cytochrome P450 superfamily (Cytochrome P450 family 4. subfamily F, member 2), is a heme-containing monooxygenase enzyme primarily expressed in the liver and kidneys. It plays a critical role in metabolizing endogenous compounds, including vitamins, fatty acids, and signaling molecules. One of its key substrates is vitamin E (α-tocopherol), which it hydroxylates to form α-tocopherol acid, a step essential for regulating vitamin E homeostasis. Additionally, CYP4F2 catalyzes the ω-hydroxylation of arachidonic acid, generating 20-hydroxyeicosatetraenoic acid (20-HETE), a bioactive lipid involved in vascular tone, blood pressure regulation, and inflammation.
The CYP4F2 gene is highly polymorphic, with specific variants (e.g., rs2108622) linked to interindividual differences in drug metabolism and disease susceptibility. Notably, these genetic variations influence warfarin dosing requirements due to altered vitamin K metabolism, highlighting CYP4F2's clinical relevance in pharmacogenomics.
Recombinant CYP4F2 protein is produced using heterologous expression systems (e.g., bacterial, insect, or mammalian cells) to study its enzymatic activity, structure-function relationships, and interactions with drugs or inhibitors. Its recombinant form enables high-purity, scalable production for biochemical assays, drug discovery, and mechanistic studies. Researchers utilize this protein to explore its role in oxidative stress, lipid-mediated signaling, and metabolic disorders such as hypertension, cancer, and cardiovascular diseases.
Structural studies of recombinant CYP4F2. including X-ray crystallography and cryo-EM, provide insights into substrate binding and catalytic mechanisms, aiding the design of targeted modulators. Overall, CYP4F2 recombinant protein serves as a vital tool for advancing understanding of lipid metabolism, personalized medicine, and therapeutic development.
