Aromatase (EC 1.14.14.14), also called estrogen synthetase or estrogen synthase, is an enzyme responsible for a key step in the biosynthesis of estrogens. It is CYP19A1, a member of the cytochrome P450 superfamily, which are monooxygenases that catalyze many reactions involved in steroidogenesis. In … See more Aromatase is localized in the endoplasmic reticulum where it is regulated by tissue-specific promoters that are in turn controlled by hormones, cytokines, and other factors. It catalyzes the last steps of estrogen biosynthesis from … See more Aromatase is expressed in the gonads, placenta, brain, adipose tissue, bone, and other tissues. It is almost undetectable in adult human See more Aromatase activity is increased by age, obesity, insulin, gonadotropins, and alcohol. It also appears to be enhanced in certain estrogen-dependent local tissue next to breast tissue, See more Aromatase in the brain is usually only expressed in neurons. However, following penetrative brain injury of both mice and zebra finches, it has been shown to be expressed in astrocytes. It has also been shown to decrease apoptosis following brain injury in zebra … See more The gene expresses two transcript variants. In humans, the gene CYP19, located on chromosome 15q21.1, encodes aromatase. The gene has nine coding exons and a number of alternative non-coding first exons that regulate tissue specific expression.
