Cytochrome P450 super family proteins are monooxygenases which catalyze multiple biochemical reactions involved in drug metabolism and synthesis of cholesterol, steroids and lipids. CYP4F3, a 60KDa protein, is a novel member of this family. It consists of a conserved heme-binding domain near the C-terminus and catalyzes the u-hydroxylation of LTB4. CYP4F3 is localized in the ER and plays a vital role in the inactivation of LTB4 and controlling inflammation. CYP4F3 exists in two functionally distinct isoforms: CYP4F3A, a neutrophil isoform, is particularly expressed in neutrophils and myeloid cells and catalyzes the microsomal u-hydroxylation of LTB4. It interacts with CD11b and myeloperoxidase on myeloid cells and regulates cellular development in bone marrow. CYP4F3B, a liver isoform, catalyzes the conversion of arachidonic acid to 20-HETE, a potent activator of PKC. Itrole hasbeen implicatedin cell proliferation, vascular tone and natriuresis.
