From: Potential utility of natural products as regulators of breast cancer-associated aromatase promoters

Partial structure of human CYP19 gene. Human aromatase gene is located on chromosome 15 and transcribes from telomere towards centromere. The aromatase gene is ~ 123 kb long contains nine coding exons (II-X) and two alternative polyadenylation sites. Partially tissue specific promoters direct aromatase gene transcription.
