Prostate-specific antigen complex. Computer model showing a molecule of prostate-specific antigen (PSA) bound to its activating antibody. Also known as gamma-seminoprotein or kallikrein-3 (KLK3),PSA is a glycoprotein that is secreted by the epithelial cells of the prostate gland. It is a constituent of semen,which it liquefies,allowing sperm to swim freely. It is also believed to be instrumental in dissolving the cervical mucus,allowing the entry of sperm to the female's uterus (womb) | |
