Summary
This gene encodes a member of the peroxidase family of proteins. The encoded preproprotein is proteolytically processed to generate the mature enzyme. Following its secretion from salivary, mammary, and other mucosal glands, this enzyme catalyzes the generation of the antimicrobial substance hypothiocyanous acid. This gene is present in a gene cluster on chromosome 17. Alternative splicing results in multiple transcript variants, at least one of which encodes a preproprotein that is proteolytically processed.

Abdominal obesity can induce local and systemic oxidative stress in PCOS and non-PCOS patients. We suggest that PCOS-induced disorders are likely to be exacerbated in the presence of abdominal obesity.
