The CYP4F11 recombinant protein is a cytochrome P450 enzyme belonging to the CYP4F subfamily, which plays critical roles in metabolizing endogenous lipids and xenobiotics. CYP4F11 is primarily expressed in the liver and, to a lesser extent, in extrahepatic tissues like the kidneys and intestines. It is involved in the oxidation of fatty acids, eicosanoids, and vitamins, particularly contributing to the metabolism of long-chain saturated and polyunsaturated fatty acids. A key function includes the hydroxylation of vitamin E (tocopherols) and leukotriene B4. linking it to inflammatory regulation and cellular antioxidant defense mechanisms.
The CYP4F11 gene is located on chromosome 19q13.2 and shares structural homology with other CYP4F members, featuring a conserved heme-binding domain and substrate recognition sites. Recombinant CYP4F11 is typically produced using heterologous expression systems like Escherichia coli or insect cell lines (e.g., baculovirus/Sf9), enabling large-scale purification for functional studies. Its recombinant form retains catalytic activity, allowing researchers to study substrate specificity, enzyme kinetics, and interactions with inhibitors or drugs.
Research on CYP4F11 has pharmacological relevance, as it may influence drug metabolism and interactions, particularly with compounds like warfarin and certain statins. Mutations in CYP4F11 have been associated with genetic disorders affecting lipid homeostasis, such as hyperbilirubinemia. Additionally, its role in vitamin E metabolism highlights potential implications in neurodegenerative diseases and oxidative stress-related conditions. Ongoing studies aim to elucidate its regulatory mechanisms and therapeutic potential as a target for metabolic or inflammatory diseases.
