【 摘 要 】
References(16)Cited-By(2)Cytochrome P450 3A (CYP3A) is the major subfamily of CYP, one of the most important metabolizing enzymes for drugs in humans and other mammals. We found two novel CYP3A genes, CYP3A131 and CYP3A132 in domestic cats (Felis catus). Both feline CYP3A proteins consist of 504 deduced amino acids and show high identity with canine CYP3A homologues and those of some artiodactyls. CYP3A131 transcripts were expressed predominantly in liver and small intestine, and to a negligible extent in other tissues, including brain, heart, kidney and lung. CYP3A132 expression was only detected in liver with much lesser amount. These results suggest the possible major role of CYP3A131 in xenobiotic metabolism including first-pass effects in domestic cats.
