Prostate-Specific Antigen

A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.

Also Known As:

Semenogelase; Prostate Specific Antigen; Seminin; Kallikrein, hK3; gamma Seminoprotein; Kallikrein hK3; gamma-Seminoprotein; hK3 Kallikrein
