Biochem/physiol Actions
Prostate Specific Antigen (PSA), a glycoprotein of the glandular kallikrein family, is a serine protease with chymotrypsin-like enzymatic activity. Circulating PSA exists in free and protease inhibitor-bound forms. Studying the ratios of free to inhibitor-bound forms may prove valuable in the diagnosis of prostate cancer.
