Cytochrome p450 2d6 isoenzymes
WebCytochrome P-450 enzymes (CYPs) are a superfamily of microsomal enzymes that are very important in the metabolism of most drugs. CYPs are prominently expressed in the liver as well as in some other tissues. CYPs normally participate in the biosynthesis and degradation of steroid hormones, lipids, and vitamins. Cytochrome P450 2D6 (CYP2D6) is an enzyme that in humans is encoded by the CYP2D6 gene. CYP2D6 is primarily expressed in the liver. It is also highly expressed in areas of the central nervous system, including the substantia nigra. CYP2D6, a member of the cytochrome P450 mixed-function oxidase system, … See more The gene is located on chromosome 22q13.1. near two cytochrome P450 pseudogenes (CYP2D7P and CYP2D8P). Among them, CYP2D7P originated from CYP2D6 in a stem lineage of great apes and humans, the … See more CYP2D6 shows the largest phenotypical variability among the CYPs, largely due to genetic polymorphism. The genotype accounts for normal, reduced, and non-existent CYP2D6 function in subjects. Pharmacogenomic tests are now available to identify patients … See more Following is a table of selected substrates, inducers and inhibitors of CYP2D6.
