The microsomal enzyme system can be activated by using an inducer drug that can bind to the receptor present in the cytoplasm or nucleus. This receptor-inducer complex then travels to the nucleus and forms a dimer. This heterodimer may bind to promoter regions of P450 genes, and increase gene expression. … See more Microsomal enzymes are typically found in the endoplasmic reticulum of hepatocytes.
