Abstract excerpt
Cytochrome P450g is polymorphic in the male rat. This polymorphism is characterized by a 20-40-fold difference in the hepatic content of P450g in the two phenotypes. Sequencing of cDNAs from high (+g) and low (-g) phenotype rats has shown that the low phenotype is due to a defective mRNA containing nine base mutations encoding 7 amino acid substitutions. To determine the role of these structural changes in the...
