Prostate-specific antigen - Wikipedia
Prostate-specific antigen (PSA, also known as kallikrein III, seminin, semenogelase, γ-seminoprotein and P-30 antigen) is a 34-kD glycoprotein produced almost exclusively by the prostate gland. It is a serine protease (EC 3.4.21.77) enzyme, the gene of which is located on the 19th chromosome (19q13) in humans. [28]
