Active Recombinant Human CYP4F3 Protein

• Cat.No.: CYP4F3-21H
• Product Overview: Recombinant human CYP4F3B and human CYP-reductase without tag was coexpressed in Escherichia coli.
  Amount: 0.5 nmol cytochrome P450

Specification

• Species: Human
• Source: E.coli
• Description: This gene, CYP4F3, encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This protein localizes to the endoplasmic reticulum. The enzyme starts the process of inactivating and degrading leukotriene B4, a potent mediator of inflammation. This gene is part of a cluster of cytochrome P450 genes on chromosome 19. Another member of this family, CYP4F8, is approximately 18 kb away. Several transcript variants encoding two different isoforms have been found for this gene.
