Enables aromatase activity. Involved in several processes, including animal organ development; carboxylic acid metabolic process; and cellular hormone metabolic process. Located in several cellular components, including dendritic spine; neuronal cell body; and synaptic vesicle. Used to study endometriosis and polycystic ovary syndrome. Biomarker of hypertension; hypothyroidism; placental insufficiency; polycystic ovary syndrome; and protein-energy malnutrition. Human ortholog(s) of this gene implicated in several diseases, including aromatase excess syndrome; bladder neck obstruction; esophagus adenocarcinoma; ovarian disease (multiple); and prostate disease (multiple). Orthologous to human CYP19A1 (cytochrome P450 family 19 subfamily A member 1). [provided by Alliance of Genome Resources, Apr 2022]
